One‑stop Sourcing for Micro‑size to Heavy‑Duty Large‑Diameter Screws & Nuts
Challenges of Producing Across a Broad Size Spectrum
Running production for both micro and large‑diameter fasteners is technically demanding. Tiny Ø1.0 mm fasteners require ultra‑precision molds, tight thread tolerance and careful handling to avoid burrs and deformation. On the opposite end, Ø36 mm heavy‑duty nuts and bolts call for high‑tonnage cold forming equipment, stable raw‑material performance and mature heat‑treatment processes to guarantee mechanical strength. Very few factories possess both sets of equipment and process experience. Most suppliers choose to concentrate on one size segment only, forcing purchasers to split orders among different workshops.
Micro‑Size Fasteners: Ø1.0 mm for Precision‑Intensive Industries
Our small‑diameter production serves precision‑focused sectors including consumer electronics, smart home hardware and precision instruments. At Ø1.0 mm, every dimension must stay within strict tolerance limits. Even minor flaws such as uneven threads or tiny burrs will cause assembly failure. Dexin Metal uses high‑precision molds and fine‑tuned cold‑forming parameters for micro‑fastener batches. We carry out strict dimensional inspection and appearance screening, making sure these miniature components fit perfectly into compact assembly spaces without sacrificing connection reliability.
Mid‑Range Sizes: Versatile Workhorse for General Industry
Between micro and heavy‑duty sizes lies our extensive mid‑diameter portfolio, widely adopted in furniture, automotive components and standard mechanical assemblies. These intermediate‑size screws, studs and nuts represent most regular sourcing demands. Thanks to our diversified machine fleet, we maintain high‑volume stable output for these items, supporting both large bulk orders and flexible mixed‑spec consolidation. Customers can combine micro, medium and large‑size parts within a single purchase order to streamline their supply‑chain management.
Large‑Diameter Heavy‑Duty Fasteners up to Ø36 mm
For heavy‑load applications such as engineering machinery, new‑energy equipment and structural assemblies, large‑diameter fasteners play a critical safety role. Our factory is capable of forming nuts and bolts up to Ø36 mm diameter. Manufacturing at this scale requires powerful cold‑forming machines, qualified high‑strength steel wire and well‑calibrated heat‑treatment workflows. Every large‑size product goes through hardness, tensile and salt‑spray testing before shipment. High mechanical performance, stable toughness and consistent thread fit are guaranteed for high‑stress operating environments.
Business Advantages for Global Sourcing Partners
Our wide‑range manufacturing capability delivers tangible benefits for procurement teams. First, customers can source micro‑, medium‑ and large‑dimension fasteners from one single manufacturer, removing the trouble of managing multiple vendors. Second, all items follow our unified full‑process quality‑control standard, avoiding quality discrepancies caused by different factories. Third, we support custom development for special dimensions within Ø1.0 mm‑Ø36 mm, whether for prototype sampling or mass‑volume roll‑out. No matter your project is miniature electronics hardware or heavy mechanical structures, Dexin Metal can match your size requirements.
