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 3/4 hex, this is the standard jam nut hex size for 1/2 inch threads.  A piece of 1 inch I.D. tubing can be slipped over the end of the wrench to be used as a handle, or a 3/8 drive ratchet can be inserted in the square hole to drive the wrench.  This wrench is manufactured from 1/4 inch thick steel for strength and reliability.  These are sold individually, and are bare steel.
