Correct tightening torque values are extremely important to assure
long Spicer Axle life and dependable performance. Under-tightening
of attaching parts is just as harmful as over-tightening.
Exact compliance with recommended torque values will assure the
best results.
The data includes fastener size, grade and torque tightening values.
Axle models are included to pinpoint identification of fasteners for
your particular axle.
To determine bolt or cap screw grade, check for designation stamped
on bolt head (see illustration).
