Maximum Wheel Fastener Torque
The wheel mounting studs used on Dexter axles conform to the SAE standards for grade 8. The
maximum torque level that can be safely applied to these studs is listed in the following chart:
Stud Size Maximum Torque
1/2”-20 UNF, class 2A 120 ft-lb (162 N-m)
9/16”-18 UNF, class 2A 170 ft-lb (230 N-m)
5/8”-18 UNF, class 2A 325 ft-lb (440 N-m)
CAUTION
Exceeding the above listed torque limits can damage
studs and / or nuts and lead to eventual fractures and
dangerous wheel separation.
