FAQ

Why a 12 point head?
A 12 point head is smaller than a hex head for the same bolt, so it fits tight spaces and counterbores, and the 12 points let a wrench grip from more angles. Use a 12 point socket.

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.
