Our jam nut wrenches are a cost effective option when looking for a large wrench to tighten the jam nuts on your build, or a compact wrench to keep in your tool box for trail repairs. This wrench is designed to fit a 1-11/16 hex, this is the standard jam nut hex size for 1-1/8 threads. A piece of 1-1/2 I.D. tubing can be slipped over the end of the wrench to be used as a handle, or a 1/2 drive ratchet can be inserted in the square hole to drive the wrench. This wrench is manufactured from 1/2 inch thick Ultra 100 steel for strength and reliability. These are sold individually, and are bare steel.
