Torque Values for Self-grounding Components
These maximum torque values must be adhered to, both for mechanical strength and to
insure the performance of the integral grounding and bonding features. It is
recommended that anti-seize compound be applied to the screw threads and a torque
wrench be used to measure the bolt torque during final assembly.
