How to Repair Cross Threaded Bolts

Cross threading occurs when the threads of a bolt shift off center and cut into the female threads of a threaded hole or nut. The cross threading damage caused by the bolt occurs in the top female threads of the threaded hole or nut. Cutting new threads on the cross-threaded bolt and the damaged female threads will repair the damage.

Instructions

1

Match a socket to the head of the cross-threaded bolt. Attach the socket to a ratchet handle. Turn the bolt counterclockwise to remove it from the part.

2

Thread the bolt into a thread gauge.

3

Select a tap matching the diameter and the thread count of the bolt into a T-handle tap wrench. Pour cutting fluid onto the threads of the tap and damaged part threads.

4

Turn the tap clockwise to thread it into the damaged part threads.

5

Set the head of the bolt in a vise with the bolt threads facing up. Lock the head of the bolt into the vise jaws.

6

Secure a die -- matching the bolts size and thread count -- into a die socket. Turn the die socket clockwise to cut new threads on the bolt.

7

Thread the bolt into the threaded part.
