FAQ
Do flange bolts need a washer?
No. The built-in flange spreads the load like a washer, so one part does the job of two and speeds up assembly.
How tight should I torque these bolts?
Torque depends on grade, size, thread and lubrication. Use the Bolt Tightening Torque Chart (PDF) on this page as a starting point.
