High Precision Lead Screws Manufacturer - Wholesale Price & Global Shipping & Custom Options

FastenMetal Ltd is a global leader in lead screw manufacturing with 15 years of expertise in the field. We specialize in producing high precision lead screws, including trapezoidal lead screws, multi-start worms, and fully customized non-standard products. Our range covers both metric sizes (M2–M24) and imperial sizes (1/4"–2.5"), supporting flexible customization from 3mm to 80mm in diameter and up to 3000mm in length, with pitch options from 0.5mm to 24mm and single to quad-start thread designs.

Our products are made from carbon steel, alloy steel (such as 38CrMoAIA), stainless steel (304/316), and high-temperature Inconel alloys. With spectroscopic analysis ensuring composition deviation within ±0.5%, our lead screws are widely used in precision-demanding applications like wafer transfer in semiconductor equipment (±0.01mm accuracy), non-magnetic transmission in medical devices, and corrosion-resistant drives in food machinery.

Equipped with 12 CNC lathes, 5-axis machining centers, and precision rolling machines, we combine cold heading and laser-assisted thread grinding to achieve lead accuracy of 0.0001mm/mm. Thanks to bulk material sourcing, our carbon steel lead screws are 15%–30% more cost-effective than industry averages. Standard orders ship in 15 days, with non-standard samples ready in 3 days and 48-hour express service available.

Our factory is ISO 9001 and RoHS certified, with over 30 inspection instruments including 3D CMMs and torque testers. With an annual capacity exceeding 500,000 units, FastenMetal Ltd proudly serves global semiconductor equipment manufacturers and cross-sea bridge projects, with proven solutions in vacuum drive systems and high-load automation 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.
