Question:
What is the Torque Requirement for 9/16inch shackle bolts
asked by: Tim
Expert Reply:
There is no specific torque rating for shackle bolts. You'll want to ensure that the bolts you use are long enough so that when installed you will have at least 2 threads protruding from the nut. Make sure that the bolt you're using has a lock nut, like part # 166081. If the bolt you are using has knurls at the bolt head, tighten the bolt down until the knurls go through the shackle link or hanger and the bolt head is flush. Then back off the nut slightly so that all of the components are pulled together but not so tight they cannot move.
