03 — BUYER GUIDE

How Wheel Locks Work

A wheel lock replaces one standard lug nut or lug bolt on each wheel. Its head has no standard hex. Instead it carries a pattern of teeth or grooves, and only the key cut to the same pattern can engage it and turn it. The top of the key is a normal hex, so the wheel is fitted with an ordinary socket on the key. Locks are an aftermarket product, sold in kits through accessory, tire and parts channels, usually under the seller's own brand.

The Key Pattern Is What Engages

There are two common designs. With an internal pattern, the key fits into a patterned recess in the lock head, which keeps the pattern protected. With an external pattern, the key wraps around teeth, splines or an irregular profile on the outside of the head. Either way, the key and the lock must mesh tightly: a loose fit lets the key slip or round off the teeth under tightening torque. The more distinct and irregular the pattern, the harder it is to remove the lock with a generic tool.

Thread and Seat Still Have to Match

Below the head, a lock is a normal lug nut or lug bolt: the thread and the seat (60° cone or ball) must match the wheel and hub, and the key must fit inside the wheel's lug hole, which matters on alloys with deep or narrow holes.

Fit with a Torque Wrench

Wheel locks should not be fitted with an impact wrench, which can damage the key and the lock teeth. Tighten to the vehicle's specified torque with a torque wrench, pressing the key straight onto the lock, and re-check the torque after the first 50 km.

Wheel Lock Questions

What does a wheel lock kit contain?

A standard kit has one lock per wheel and a matched key. The number of locks, the key style and the packaging are set to your order.

Can you pack wheel locks under our brand?

Yes. Locks and keys can be packed in blister cards or retail boxes with your brand, artwork and barcode.

Which threads and seats are available?

Lock nuts in M12×1.5, M12×1.25, M14×1.5 and 1/2″-20 UNF with 60° cone seat; lock bolts in M12×1.5, M12×1.25, M14×1.5 and M14×1.25 with cone seat, and in M12×1.5 and M14×1.5 with ball seat. Other sizes are made to sample.

Can wheel locks be fitted with an impact wrench?

No. An impact wrench can damage the key and the lock teeth. Fit them with a torque wrench to the vehicle's specified torque, and re-check after the first 50 km.

Can you match an existing lock kit?

Yes. Send a sample kit and we measure thread, seat, length and the key pattern, then make samples for your approval.

5,000 pieces per specification, low enough for a test order or a new range, and different specifications can be shipped together in one container.
