Strength 10.9 Alloy Steel Black Plated Silver Dacromet Car Wheel Screws M10X1.5X35

This socket head cap screw is used to mount the hub/wheel bearing to the suspension spindle/post.

It screws in from the back of the suspension uprights (usually you need 4 per hub).

BMW recommends replacing these screws with any new hub. This is an M10x1.5 thread, 35mm long, with a hexagon socket head.

The wheel bearings on these cars are mounted with this M10x1.5 bolt or M10x1.25 bolt.

Bearings/hubs and bolts have to match together, so you may not be able to reuse existing bolts on new hubs.

If your wheel bearing is 2017 or newer, it probably has a 1.25 pitch.

10B21 material introduction

10B21 Cold Heading Steel

10B21 cold heading steel chemical composition C (carbon): 0.18 ~ 0.23; Si

(silicon): ≤0.10; Mn (manganese): 0.70 ~ 1.00; P (phosphorus): ≤0.030; S

Cold forging steel, good plasticity, strength is not too high, heat treatment

effect is obvious. Performance and 20 steel are better, It is generally used on

automobile wheels, processing fasteners or other structural parts.
