FastenMetal Ltd – Precision Lead Screw Manufacturing Specialist

FastenMetal Ltd is a leading manufacturer with 15 years of experience in producing high precision lead screws. We specialize in trapezoidal lead screws, multi-start worm screws, and custom non-standard designs, offering both metric (M2–M24) and imperial (1/4"–2.5") specifications. Our products support diameters from 3mm to 80mm, lengths up to 3000mm, and lead pitches ranging from 0.5mm to 24mm, accommodating single to quadruple thread starts.

Utilizing materials such as carbon steel, 38CrMoAIA alloy steel, stainless steel (304/316), and Inconel high-temperature alloys, we ensure precise chemical composition control with deviations within ±0.5%. This precision meets the stringent requirements of various industries, including semiconductor equipment (with positioning accuracy of ±0.01mm), medical devices (non-magnetic transmission), and food machinery (corrosion-resistant transmission).

Our facility is equipped with 12 CNC lathes, five-axis machining centers, and precision rolling equipment. By integrating cold heading and laser feedback thread grinding processes, we achieve a lead accuracy of 0.0001mm/mm. Certified with ISO 9001 and RoHS, our quality assurance includes over 30 inspection devices, such as coordinate measuring machines and torque testers. With an annual production capacity exceeding 500,000 units, FastenMetal Ltd serves global clients in semiconductor manufacturing and large-scale infrastructure projects, providing reliable solutions for vacuum transmission systems and high-load automated production lines.

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.
