Inside almost every package of materials I’ve ever signed off on, Chinese fastener factories are present, ranging from small screws for a phone to large bolts on oversized parts of duct tape.
It is challenging to imagine a substitute for the Chinese fastener industry, which occupies tens of thousands of miles in the global supply chain. Two decades ago most of these plants stamped out commodity hex bolts; today many ship into critical infrastructure projects and hold the international quality standards their overseas buyers ask for (ISO, IATF, DIN, ANSI). Here is a rundown of Chinese fastener manufacturers, organized by their output, technical expertise, and export presence, with approximately 20 to choose from. First things first, a “top 20” list published never corresponds with the actual figures in their buying process. By ignoring self-reported capacity, breaking down samples, and trading companies reselling other plants’ output, the list can be considered as a shortlist starter to ensure accuracy.
1. JM Hardware® (Shanghai Jian & Mei Industry & Trade Co., Ltd.)
Founded: 2006 Headquarters: Shanghai Exports to: 85+ countries Customer base: 1,200+ clients globally Certifications: ISO 9001:2015, trademarked in U.S., EU, UKProducts and Capabilities
High-strength fasteners, such as bolts and nuts with high strength, are the primary focus of JM Hardware®. Washers and pins Custom screws Stainless steel, alloy steels, aluminum alloys (Al2O3), copper (C3O4) and other metals have unique fasteners. There are more cold-headers than the plants I have visited that use this type of process, which covers a wider area.Global Reach and Market Position
Customs data tells a coherent (if jagged) export story: 2024: 173 export records across 15 partners in 8 regions 2023: 75 export records across 8 partners in 5 regions 2022: 129 export records across 16 partners in 7 regions Socket screws have been sent to India and fastener components are being shipped to Mexico in the latest update.Buyer Notes
The multilingual sales team for global accounts is one of the three things I noticed during my own sourcing trips to this Shanghai-based exporter. Lower production costs with direct factory pricing. The document side of the logistics is backed by global experts. Personalized services for specific functions. Honest caveat: customs-record counts are a proxy, not revenue. A 173-record year can mean many small shipments rather than a few large strategic accounts, and dips like the 2023 drop usually trace back to one big buyer rotating suppliers, not a quality issue.

Founded: 1999 Location: Yuyao, Zhejiang Certifications: ISO 9001:2015, RoHS, SGS, Bureau VeritasProduct Excellence
Screw-centric: OuKaiLuo’s self-tapping and self drilling screws are its specialty. Security screw, machine screw Special purpose deck screws Substances under cold heading and stamping substances. From 0.8 mm and beyond, production can be achieved. This class of products has a reported defect rate of 200 PPM, which is very low, and shipping into retail and OEM markets in the EU is also RoHS compliant.Manufacturing Capabilities
Cold pier machines for precise forming would be typical equipment on the shop floor. Embroidered thread rollers for precise attachment. A variety of metal presses are utilized. Qualifiers of optical testingWhere Buyers Get Burned
The Yuyao-area screw suppliers present two practical risks that I am constantly aware of. PPM is only countable if it is measured on a real production batch, as the sample lot is typically superior to the bulk lot. The small plants can experience a gradual decline in the steel source when the wire-rod price rises by several hundred RMB per ton, and buyers are only notified during salt-spray or torque testing after some weeks.3. Jiaxing Qimu Trading Co., Ltd.
Certifications: ISO 9001 certified Production capacity: 20,000+ tons annuallyProduct Range
The catalog of Qimu Trading features thread rods of varying specifications, including both OEM and typical jobsite options. Various types of screws, nuts, and bolts. Screws for mounting drywall and anchors. Personalized manufacturing using client-generated sketches.Compliance and Global Reach
Output is built to DIN, ANSI, and ISO standards, with shipments going to: America and Europe Russia and Australia Asia and AfricaTrading Company vs. Factory
“Trading Co., Ltd.” is the meaning behind its presence in the name. It appears that trading houses in Jiaxing frequently combine the production of three or four local plants into one quality. When a bad lot is located, it can take weeks to identify the sub-plant that produced the lot, which has negative implications for traceability as it increases breadth and delays your warranty claim.4. Hisener Industrial Co., Ltd.
The history of Haining, Zhejiang was characterized by its origins in the production of threaded rods and later on, it evolved into a comprehensive range of fasteners.Product Offerings
The range of Hisener includes screws and threaded rods. Bolts and nut, along with washers. Building application anchors Brass and stainless steel are composed of various metals.Innovation and Sustainability
This is a technical headline, and the bi-metal type of screw has been designed to combine stainless steel and carbon steel so that it will resist corrosion on its surface and provide tensile strength in the shank. Energy and waste-related ESG initiatives are also covered by Hisener.A Buyer-Side Observation
At the welded interface, the quality of the bi-metal screws remains or diminishes. When I was in “ESG-certified” plants, the welder station remained as bottleneck, with yield numbers being slowly integrated into hardness check rejection rate. Provide the hardness profile of the weld-zone, not just the surface coating spec.Lorem ipsum dolor sit amet, consectetur adipiscing elit.

5. SUNO Group Limited
Founded: 1990 Certifications: ISO 9001 & IATF/TS 16949 Association: Member of China Fasteners InstituteProduct Specialization
SUNO Group’s output covers: Hex bolts and flange bolts Tapes and machine screws are both present. Install bolts and studs with glue. Design elements and individualized adhesives.Market Presence and Scale
Automotive and railway sectors are among the end markets. The fields of electronics and construction.

The IATF/TS 16949 mark is the one that actually matters for any Tier-2 automotive PO; the ISO 9001 alone would not be enough.6-20. Other Prominent Chinese Fastener Manufacturers
Before the table, a brief caution: the “top 10″ and ” top 20″ rankings in this sector are predominantly created by advertising agencies and trade portals. Their usefulness is not as procurement gospel, but rather as a shortlisting tool. Below is the actual source data for all names, rankings and certification claims, so please verify each one.
