Precision Brass Half Nuts at Competitive Prices - Custom Manufacturer FastenMetal Ltd

FastenMetal Ltd is a professional manufacturer with 15 years of deep expertise in brass fasteners, specializing in the production of high-precision brass half nuts. Our product range includes full metric sizes (M3–M20) and imperial sizes (1/8"–1"), supporting global thread standards such as ISO 261, BSW, and UNC/UNF.

We use high-conductivity brass grades (BS 249/IS 319) and manufacture through cold forming to ensure thread tolerance within ±0.02mm. Standard anti-corrosion finishes include tin or nickel plating, resistant to up to 2,000 hours of salt spray, with optional surface treatments such as Dacromet and zinc-aluminum coatings—up to eight finish options in total.

With excellent electrical conductivity and resistance to magnetic interference, our brass half nuts are widely used in mechanical transmission systems (shaft positioning), new energy battery modules (anti-electrolysis connections), smart home assemblies (concealed fittings), and medical devices (sterile installation environments). We support custom production based on drawings, including non-standard thread lengths and special bore shapes (e.g., stepped internal threads).

Through large-scale procurement and fully automated production lines, we reduce costs by 15%–30% compared to market averages. FastenMetal Ltd has delivered high-value solutions to over 50 automotive component suppliers and 18% of global wind energy projects. All products come with RoHS certification and full material reports.

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.
