How to Choose the Right Wheel Stud
A wheel stud is the threaded pin that stays in the hub; the wheel goes over it and a lug nut clamps it in place. Most cars from Asian and American makers use studs. Buyers rarely choose a stud by "type": they start from a vehicle, a drawing or a sample, and the stud has to match the hub and the nut exactly. When you send us one of these, this is what we confirm before quoting.
The Knurl Has to Fit the Hub
A press-in stud is held by its knurl, the ring of serrations under the head. The knurl diameter must match the hole in the hub flange: too small and the stud spins when the nut is tightened, too large and it cannot be pressed in without damaging the hub. Common knurl diameters on passenger cars run from about 12.4 to 15.7 mm.
Then Thread, Length and Head
The thread must match the lug nut, for example M12×1.5, M12×1.25 or 1/2″-20 UNF. Length is measured from under the head to the tip; thicker aftermarket wheels and slip-on wheel spacers need longer studs so the nut still has full thread engagement. The head diameter and shape must clear the brake parts behind the hub.
What to Send Us
A drawing, a sample, or the vehicle make, model and year. If you sell slip-on wheel spacers or thick aftermarket wheels, tell us the extra thickness and we will propose the length.

Wheel Stud Questions
Can you make wheel studs to my drawing or sample?
Yes. Send a drawing, a sample or the vehicle details and we confirm thread, knurl diameter, length and head before quoting.
What is the difference between press-in and screw-in studs?
Press-in studs are held in the hub by a knurl and are the usual factory design. Screw-in studs thread into a hub made for bolts and are used for bolt-to-stud conversion and with wheel spacers.
How long should a replacement stud be?
Start from the original length. For thicker aftermarket wheels or slip-on wheel spacers, add the extra thickness so the lug nut keeps full thread engagement.
Which finish lasts longest?
Dacromet, Magni or zinc-nickel give the longest corrosion life. Zinc is rated 96 h+ in neutral salt spray, and every lot is salt-spray tested.
What is your MOQ?
5,000 pieces per specification. That is low enough for a test order or a niche vehicle range, and different specifications can be shipped together in one container.
