Our core business since 2009. We cold-forge and machine wheel nuts, bolts and studs for passenger cars, SUVs and light trucks, for OE replacement and the aftermarket, in every common thread, seat and finish.
Six product families cover the wheel-mounting hardware of a passenger car. Open any type for a buying guide, vehicle fitment and answers to common questions.

Acorn, bulge, flat-seat and tuner lug nuts for steel and alloy wheels, open or closed end.
02
Wheel bolts for European platforms with cone, ball (R12 / R13 / R14) and flat seats.
03
Anti-theft lock nuts and bolts with a matched key, plus spline-drive nuts for tuner wheels.
04
Press-in knurled hub studs and screw-in studs, made to OE drawings or samples.
05
Hub-centric aluminum spacers and PCD adapters, bolt-on or slip-on.
06
Plastic and aluminum rings that center aftermarket wheels on the hub.

Plants with their own plating line usually master one or two coatings. We work with a network of specialized partner plants instead, so we can offer every common finish and keep each one under our own inspection.







Multi-station headers form nuts, bolts and studs from wire rod.
Threads, seats and hex profiles turned to drawing tolerances.
Hardened and tempered to the required strength class by partner plants, checked by our QC.
Done by long-term partner plants, audited and controlled by our QC.
Thread, dimension, salt-spray and appearance checks before shipping.
We match the part, make samples for approval, then produce to that standard.

Yes. Send a drawing, an OE part number or a physical sample. We confirm seat type, thread, hex size, length and finish, then make samples for approval before mass production.
Zinc for cost-sensitive volume, Dacromet or Magni for long corrosion life, black zinc, zinc-nickel or black e-coat for black wheels, chrome or anodized aluminum for the accessory market. We can advise based on your market and salt-spray requirement.
No single plating line can cover every finish well. We work with specialized partner plants for each coating, so you get one supplier for zinc, Dacromet, chrome, black and anodized parts, with our own incoming inspection and salt-spray testing on every lot.
5,000 pieces per specification for nuts, bolts, studs, locks and hub rings, and 100 pieces for wheel spacers, low enough for test orders and niche vehicle ranges. Lead time is usually 40–60 days after sample approval, depending on finish and quantity.
Yes. Bulk cartons, retail boxes, blister packs and lock kits can be packed under your brand and barcode.
