Wheel bolts & Wheel nuts – For each wheel spacer the matching bolts
For mounting the wheel spacer systems D1, D2, DZ and DZX we recommend ST wheel bolts in black or silver. Note that the length of the bolts depends on the thickness of the selected wheel spacer. In addition the type of screw seat and thread must be considered.

Important note! Minimum thread engagement must be considered in all cases:

- M12x1,25 min. 8,0 turns
- M12x1,5 min. 6,5 turns
- M12x1,75 min. 6,5 turns
- M14x1,25 min. 9,0 turns
- M14x1,5 min. 7,5 turns
- M15x1.25 at least 10.0 turns
- 1/2“ min. 8,0 turns

Caution:
A too long wheel bolt may cause damage at the axle components.
