Bolt Torque Specifications

The specification torque table below will help the installer determine how tight a specific bolt must be. A
bolt that has been over tightened can be just as dangerous as one that hasn't been tightened enough.

IMPORTANT: Bolts should not be tightened in excess of the torque specifications chart listed below.
