High-Precision Bolt & Nut Manufacturer - Custom Fasteners M3–M64

Fastenmetal Ltd is a professional fastener manufacturer with 15 years of deep industry expertise, focused on the R&D and production of high-precision bolts and nuts. Backed by a modern production facility and a complete in-house manufacturing system, we are equipped with a full range of automated cold heading machines (supporting M3–M64 sizes), 5-axis CNC machining centers, and continuous heat treatment furnaces.

Combining precision cold heading and quenching & tempering processes, we ensure strength grades ranging from 8.8 to 12.9. In addition to carbon steel, alloy steel, and 304/316 stainless steel, we now offer specialty materials such as titanium alloys and weathering steel, with raw material composition strictly monitored via spectrometers.

We provide 8 anti-corrosion finishing options including zinc-aluminum coating, Dacromet, and hot-dip galvanizing. Our zinc-aluminum line offers up to 2,000 hours of salt spray corrosion resistance. Over 30 testing instruments—including 3D coordinate measuring machines and friction coefficient testers—ensure tolerance control up to ±0.01mm.

We support drawing-based customization for special flange fasteners, extended threaded components, and other non-standard parts. A quick-change die system allows us to deliver samples in 3 days and fulfill standard orders in just 5 days.

Certified with ISO 9001 and IATF 16949, Fastenmetal provides cost-effective fastening solutions for global clients in construction machinery, new energy, and other industries. Scaled production enables a 15%–30% reduction in procurement costs compared to the industry average. All products are delivered with SGS certifications and material reports, widely used in automotive, bridge, and wind power applications.

Are You an OEM Manufacturer?

Yes

Fasteners & Stamping Parts Supplier

Fastenmetal is a experienced manufacturer produce fasteners and stamped metal parts. We specialize in OEM production based on customer drawings, offering both standard and custom made solutions.

Our fastener range includes car bolts, marine bolts, chemical bolts, stud bolts, threaded rods, and other high strength bolts.

1.Exotic Material Bolts

For bolts used in extreme environments such as marine, chemical, oil & gas, and aerospace industries,normally need higher corrosion resistance. FastenMetal supply custom bolts and metal components made from exotic materials such as Inconel, Monel, Titanium, and various types of duplex stainless steel.

2.High Strength Bolts

When regular bolts don’t meet strength requirements, we can produce bolts with strength grades up to Grade 12.9 for your requirements.

3.Custom Shapes and Sizes

We manufacture fasteners in special shapes, lengths, and diameters according to specific applications—fully customized according to your drawings.

In addition to fasteners, we offer custom stamping and metal fabrication services. We have 12 punching machines and press machines for large sheet metal forming and bending, we can handle part thicknesses up to 6mm.

In many of these cases, the customer’s engineering department will provide us CAD drawings and tell us the materials,strength grade they need. We produce samples for customers approval before bulk production.
