The ST threaded bolts are used to mount the AZX system. The ST threaded bolts (screw-in bolt with double thread) enable an easy conversion from wheel bolts to wheel studs. In the AZX-spacers are common threaded sleeves that are used for bolt-on systems for vehicles with wheel nuts. While installation the ST threaded bolts are screwed into these threaded sleeves. Now the AZX wheel spacers can be used for vehicles with wheel studs. The ST threaded bolts are available in different thread types so that the original wheel nuts can be used.

Important note! Minimum thread engagement must be considered:

M12x1,25 at least 8,0 turns
M12x1,5 at least 6,5 turns
M12x1,75 at least 6,5 turns
M14x1,25 at least 9,0 turns
M14x1,5 at least 7,5 turns
1/2" at least 8,0 turns

Caution:
Wheel bolts that are too long may cause damage at the axle components.
