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. Lbs.
9/16"-18 UNF, class 2A 170 Ft. Lbs.
5/8"-18 UNF, class 2A 325 Ft. Lbs.
!
CAUTION
Exceeding the above listed torque limits can damage studs and/or
nuts and lead to eventual fractures and dangerous wheel separation.
CAUTION
Dexter’s patented Torq-N-Go
™
swiveling wheel nut generates
significantly more clamp load than standard wheel nuts. Do not
exceed the specified torque or the wheel and/or stud may be
damaged. Special caution should be observed with steel wheels.
Some steel center discs may not be able to withstand the Torq-N-Go
™
wheel nuts’ specified operating torque. It is the responsibility of the
trailer manufacturer to assure that its’ wheels are compatible with
this wheel nut.
