How do you know if a bolt is reverse threaded?
Bolt Basics Most bolts have a right-handed thread and turn in a clockwise direction as you screw them in.

Reverse-thread bolts have a left-handed thread and turn in a counter-clockwise direction when tightened.
How can I loosen a loose U-bolt on my rear axle?
