Wheel Nuts for European Trucks & Trailers

Most heavy trucks and trailers in Europe run on M22×1.5 thrust plate nuts. What changes is the hex, the height and the sleeve.

04 — BUYER GUIDE

How to Choose the Right Truck Wheel Nut

Truck wheel nuts look alike, but they are not interchangeable. Before anything else, check how the wheel is centered and how the nut seats against it.

Flat Seat or Ball Seat

Most European trucks, buses and trailers today use the flat-seat (ISO) system: the wheel is centered on the hub, and the nut clamps it through a captive thrust plate (DIN 74361-3). The plate turns freely, so the clamp load is spread over the wheel face and not lost to friction. Older vehicles and some trailers use the ball-seat system (DIN 74361-2): a spherical nut, or a flat nut with a Limes spherical ring.

Steel or Alloy Wheels

Alloy wheels are thicker at the bolt holes than steel wheels, so they need a thrust plate nut with a sleeve. The sleeve length (short K or long L) depends on the wheel and the stud length. A nut made for steel wheels on an alloy wheel will not clamp correctly.

Thread, Hex and Height

M22×1.5 is the most common thread on heavy trucks and trailers; M18 and M20 appear on lighter trucks, and 7/8″ BSF or UNF on some older vehicles. Hex 32 mm is the most common, but some makes use hex 33, so the right socket matters in the workshop. Height follows the stud length.

Finish

Our truck wheel nuts are mostly finished in zinc flake coatings such as Delta-Protekt, Geomet, Magni and Zintek. Zinc flake is applied without electrolysis, so there is no risk of hydrogen embrittlement on high-strength class 10 nuts.

Torque and Re-Check

Tighten to the torque given by the vehicle or axle maker, in the correct sequence, and re-check after the first 50–100 km, when the wheel has settled.

What to Send Us

An OE number, a vehicle or axle list, your wheel type (steel or alloy), or a sample nut. We match thread, seat, hex, height, plate and sleeve.

06 — FAQ

Truck Wheel Nut Questions

What is the difference between DIN 74361-2 and DIN 74361-3?

DIN 74361-2 covers ball-seat nuts, flat nuts and Limes spherical rings. DIN 74361-3 covers flat-seat nuts with a captive thrust plate, with or without a sleeve, used on most European trucks today.

Which nut do I need for alloy truck wheels?

A thrust plate nut with a sleeve. Alloy wheels are thicker at the bolt holes, so the sleeve length must suit the wheel and the stud. Send the wheel and vehicle and we match it.

Hex 32 or hex 33?

Both are used with M22×1.5. Hex 32 is the most common; some makes use hex 33. Check the OE part or send a sample.

What strength class are your truck wheel nuts?

Class 10.

Can you match a nut from an OE number or sample?

Yes. Send the OE number, a drawing or a sample, and we match thread, seat, hex, height, plate and sleeve.

What is your MOQ?

10,000 pieces per size.

Do you make truck wheel bolts too?

Yes, see our truck wheel bolts: serrated bolts for ISO hub-piloted wheels and JIS dual-wheel bolts, made with their matching nuts.
