China produces roughly half the world’s industrial fasteners, with the country’s fastener market generating over $22 billion in revenue in 2025. That scale means you’ll find hundreds of screw manufacturers in China, nut and bolt producers, and general-purpose fastener factories. But the range in quality, capability, and reliability across those suppliers is enormous.
The eight manufacturers below match different sourcing needs. Whether you’re buying standard hex bolts in bulk, ordering custom-machined fasteners to a specific tolerance, or qualifying a new supplier for an automotive program, this guide helps you compare them based on what actually affects your purchasing decision: certifications, minimum order requirements, process capability, and material range.
What Should You Look for in a China-Based Fastener Manufacturer?
Not every fastener supplier operates the same way, and picking the wrong model for your project creates problems that don’t show until parts arrive. Before comparing individual manufacturers, get clear on five things:
- Standard vs. custom fasteners: Some factories are set up for high-volume production of catalog fasteners (DIN, ISO, ANSI standards). Others specialize in custom-manufactured fasteners, machined or forged to your drawing. The quoting process, lead times, and pricing structures differ significantly between the two.
- Material and grade requirements: If you need stainless steel, alloy steel, titanium, or specialty grades, confirm the manufacturer’s material sourcing and testing capabilities upfront. Ask for mill certificates.
- Certifications that matter for your industry: ISO 9001 is a baseline. Automotive programs typically require IATF 16949. Medical applications need documented traceability. Don’t assume certifications – verify them.
- Order volume flexibility: Some manufacturers won’t quote below 10,000 pieces. Others handle prototype quantities of 50 to 100 parts. Your project stage determines which suppliers are a fit (some have no Minimum Order Quantity (MOQ).
- Surface treatment and finishing: Zinc plating, hot-dip galvanizing, phosphating, dacromet. The treatment affects corrosion resistance, torque behavior, and cost. Confirm in-house capability vs. outsourced finishing.
The eight manufacturers below cover the full range of these variables.

The 8 Manufacturers: Full Profiles
1. XTJ CNC
XTJ CNC is a precision CNC machining and manufacturing partner that produces custom fasteners to your exact specifications. Bolts, screws, nuts, studs, standoffs, inserts, and specialty hardware machined from the material you need.
Standard fastener factories run cold heading and thread rolling lines optimized for high-volume catalog parts. When you need a fastener in an unusual material, a non-standard thread pitch, a tighter tolerance than off-the-shelf provides, or a geometry that doesn’t exist in any catalog, CNC machining is the process that fills the gap.
Where standard fastener manufacturers hand you a catalog, XTJ CNC starts with a Design for Manufacturability (DFM) review of your drawing. They flag thread form issues, material selection tradeoffs, and finishing sequences before machining begins.
Best for: Engineers and procurement teams sourcing custom-machined fasteners, specialty hardware, or non-standard bolts and screws where off-the-shelf options don’t meet the spec.
2. Hisener Industrial
Hisener operates out of Zhejiang, one of China’s major fastener manufacturing clusters. They produce a broad range of screws, bolts, threaded rods, and specialty fasteners. Their product line covers self-drilling screws, drywall screws, machine screws, and structural bolts, with export reach across Europe, North America, and Southeast Asia.
Hisener’s strength is volume production of standard and semi-custom screw types. They run cold heading, thread rolling, and heat treatment in-house, which gives them tighter control over lead times for large orders. Hisener holds ISO 9001 certification across their production lines.
For buyers ordering standard screws in China at production volumes, Hisener offers a reliable combination of a broad product range and established export logistics. If you need fully custom geometries or specialty alloys, confirm their engineering capability for your specific part before committing.
Best for: Procurement teams sourcing standard and semi-custom screws at medium-to-high volume who want an established exporter with a broad product catalog.
3. DT Fastener (DATIAN)
DT Fastener, also known as DATIAN High Strength Nuts, is a member of the China Fastener Industry Association. They specialize in high-strength hex nuts, flange nuts, nylon lock nuts, and heavy hex nuts.
Their focus is narrow and deep. DT doesn’t try to be a full-range fastener supplier. They only produce nuts, and they produce them at scale with consistent heat treatment and mechanical properties.
DT Fastener’s catalog runs primarily to DIN, ISO, and GB standards. If you’re sourcing standard high-strength nuts for structural, automotive, or industrial applications, they’re a strong option. For custom nut geometries or non-standard materials, you’ll likely need a manufacturer with CNC machining capability rather than a cold forging specialist.
Best for: Buyers sourcing standard high-strength nuts at high volume for structural or industrial applications.
4. Ningbo Teng Qi Fasteners
Ningbo Teng Qi operates from Ningbo, another major fastener production hub in China. They produce hex bolts, carriage bolts, U-bolts, anchor bolts, nuts, washers, and threaded rod. Their product range leans towards construction and industrial hardware.
They offer some custom manufacturing for modified standard fasteners. Their ISO 9001 certification covers their production process, and they export regularly to North America and Europe.
Teng Qi works well for construction and industrial buyers ordering medium volumes of standard bolt and nut combinations. Their modified-standard capability fills a useful middle ground between pure catalog suppliers and full-custom manufacturers.
Best for: Construction and industrial buyers who need standard bolts, nuts, and anchors with options for modified specifications.
5. WanHong Fastener
WanHong produces a wide catalog of screws, nuts, rivets, threaded rods, and washers from their manufacturing base in China. They cover a broad standard fastener range, including machine screws, self-tapping screws, socket head cap screws, hex bolts, and blind rivets.
Their pricing is competitive for standard catalog items, and they offer zinc plating, galvanizing, and black oxide finishing. WanHong is suited for buyers who need multiple fastener types from a single source and prefer consolidating orders rather than managing separate suppliers for each category.
If your fastener requirements are standard and your priority is order simplification at competitive pricing, WanHong covers a lot of ground. For precision or custom work, you’ll want a different type of manufacturer.
Best for: Buyers who want to consolidate standard fastener purchasing across multiple categories from a single supplier at competitive pricing.
6. AYA Fasteners
AYA Fastener operates out of Hebei province and supplies bolts, nuts, screws, washers, and anchors. They offer competitive pricing on standard fasteners and accept a wider range of order volumes than some of the larger, high-volume-only factories.
Their flexibility on order size makes them worth considering if you’re testing a new supplier or placing initial orders before committing to a long-term sourcing arrangement. AYA’s facility operates under ISO 9001, with some customization available on non-standard lengths, materials, and coatings.
AYA’s pricing positions them toward the budget end of the spectrum. As with any budget supplier, verify material certifications and mechanical test reports on your first order before scaling up.
Best for: Cost-conscious buyers sourcing standard fasteners at flexible volumes who want a lower entry point for testing a China-based supplier.
7. Ningbo Fastenwell
Fastenwell specializes in stainless steel fasteners, including hex socket head cap screws, set screws, machine screws, and specialty stainless bolts. They also produce carbon steel and alloy steel fasteners, but their stainless range is where they’re most competitive.
For applications where corrosion resistance is a primary requirement – marine hardware, food processing equipment, outdoor infrastructure, chemical handling – a supplier with deep stainless steel expertise matters. Fastenwell’s focus on stainless means their material sourcing, heat treatment, and finishing processes are tuned for those grades.
They’re based in Ningbo with ISO 9001 certification and established export channels to Europe and North America. For stainless steel screw orders at medium volume, they’re a strong specialist pick.
Best for: Buyers who need stainless steel screws and bolts for corrosion-critical applications and want a specialist supplier rather than a generalist.
8. Kinfast
Kinfast offers custom screw manufacturing alongside their standard catalog. They produce self-drilling screws, self-tapping screws, machine screws, and proprietary screw designs. This means they’ll work from your drawing to produce a fastener geometry that doesn’t exist in standard form.
Their custom design capability sets them apart from pure catalog manufacturers. If you have a proprietary product that requires a fastener designed specifically for your assembly, Kinfast’s engineering team can work through the design and prototyping process before moving to production.
Like most China-based screw manufacturers, they’re ISO 9001 certified. Their strength is the overlap between custom design support and production-scale manufacturing: a combination that’s harder to find than it sounds, since most custom shops are small and most large factories only run standard parts.
Best for: Product teams that need a custom-designed screw or specialty fastener produced at scale, with engineering support during the design phase.
How to Choose the Right China Fastener Manufacturer
Every supplier on this list fills a different sourcing need. Getting to the right shortlist quickly means matching your project requirements to the right manufacturing model. Here are five criteria worth evaluating before you commit:
Are you buying standard or custom fasteners?
If you need DIN, ISO, or ANSI standard fasteners in production volumes, a cold heading factory like DT Fastener or WanHong delivers the best cost-per-piece. If you need a non-standard thread, an unusual material, or a geometry that doesn’t exist in catalogs, you need a CNC machining partner like XTJ CNC that produces fasteners from your drawing.
What material and grade do you need?
Standard carbon steel and stainless steel fasteners are widely available. Specialty alloys – titanium, Inconel, brass, bronze – narrow the field considerably. The global industrial fasteners market continues to grow, driven partly by demand for specialty-material fasteners in the automotive and electronics sectors. For specialty materials, confirm the manufacturer can source the raw material, provide mill certifications, and machine it to your tolerance requirements.
What certifications does your application require?
ISO 9001 is a minimum. If you’re supplying fasteners into an automotive program, IATF 16949 is typically mandatory. For medical or regulated industries, traceability from raw material through final inspection becomes non-negotiable. XTJ CNC holds both ISO 9001 and IATF 16949, with CMM inspection and full documentation for every production run.
What’s your order volume?
High-volume standard fasteners favor cold heading manufacturers. Low-volume custom fasteners, prototype hardware, or bridge production favor CNC machining. If you’re at the prototype stage and don’t want to commit to a 10,000-piece minimum, prioritize manufacturers with no MOQ policy.
How do you evaluate quality before committing?
Request first article inspection reports, material test certificates, and dimensional inspection data before scaling any order. A reliable manufacturer provides these without pushback. If a supplier hesitates on documentation, treat that as a signal — not a negotiation point.
How Fastener Manufacturing Processes Affect Your Decision
The eight manufacturers above use different production processes, and the process determines what they can, and can’t, make cost-effectively at your order volume.
Cold heading and thread rolling
Standard catalog fasteners are produced on cold heading and thread rolling lines. Wire stock feeds into a die, where the head shape is formed through impact, and then threads are rolled rather than cut. This process is fast and produces strong, repeatable parts at extremely low per-piece cost, but only at volume. Tooling costs make small batches expensive.
Use cold heading manufacturers (Hisener, DT Fastener, WanHong, AYA, Teng Qi) when you need standard DIN, ISO, or ANSI fasteners in quantities of 10,000+ pieces.
CNC machining
CNC machining produces fasteners by cutting threads and forming features directly from bar stock or billet. Per-piece cost is higher than cold heading, but there’s no tooling investment, and the process handles non-standard geometries, unusual materials, and tight tolerances that cold heading can’t.
Use CNC machining (XTJ CNC, Kinfast for design work) when you need custom geometries, specialty alloys, prototype quantities, or features outside standard catalogs.
When to combine both
Some fastener programs use cold-headed standard fasteners for bulk hardware and CNC-machined custom fasteners for assembly-critical components. Splitting the order between two suppliers can deliver the cost efficiency of cold heading on the standard parts and the precision of CNC machining where it matters most.
Ready to Source Custom Fasteners from China?
The right fastener manufacturer depends on whether you’re buying standard or custom, what material and certifications your application requires, and how much volume flexibility you need at the start of the relationship.
If your project calls for custom-machined fasteners (non-standard threads, specialty materials, tight tolerances, or unique geometries), reach out to XTJ CNC. We’ll review your drawing, confirm material availability and process capability, and give you a clear production timeline. No minimum order quantity, and your DFM review is included.

Fastener Manufacturers in China FAQs
Can a China-based screw manufacturer match the quality of domestic suppliers?
Yes, with the right supplier selection. Quality comes down to the manufacturer’s process control, certifications, and inspection practices. A China-based fastener manufacturer with ISO 9001 certification, documented heat treatment processes, and CMM inspection can match or exceed the consistency of domestic suppliers.
What’s the typical lead time for ordering fasteners from China?
Standard catalog fasteners from an established manufacturer typically ship within two to four weeks, depending on stock availability and order size. Custom-machined fasteners take longer. Expect five to 15 business days for manufacturing, plus international transit time.
How do I verify that a China fastener manufacturer’s certifications are legitimate?
Ask for copies of the ISO or IATF certificates and cross-check the certificate number with the issuing body’s online database. Reputable certification bodies like TÜV, SGS, and Bureau Veritas maintain searchable registries. If the certificate can’t be verified online, that’s a disqualifying finding. You can also request a virtual or in-person factory audit before committing to a long-term supply agreement.
Is it cost-effective to order custom fasteners from China in small quantities?
It depends on the manufacturing process. Cold heading and thread rolling require tooling, which makes small quantities expensive per piece. CNC machining doesn’t require dedicated tooling, so custom fasteners in quantities of 50 to 500 pieces are cost-effective when produced on a CNC lathe or mill. For small-batch custom fasteners, a CNC machining service with no minimum order quantity is typically the most practical route.
