The Bolt-Up System Barrel Nut Wrench is a proprietary spanner wrench required to install our Bolt Up System Barrel Nut. This wrench is designed to be used with a 1⁄2 Drive Torque Wrench.
This is the original aluminum single-use wrench. Care must be taken to make sure you turn it, while pulling the wrench, and not pushing it. Some call it closing the C.
