Hook Wrench

Hook wrench function is assembling the lock nuts from sleeves. Hook wrenches are used to tighten, loosen, or hold machinery components that are round but also notched or multi-faceted, such as lock nuts and pipe fittings.

Whether a hook wrench's head or hook, is fixed in place or adjustable, the inner side of its curve usually ends in a small, downward-pointing tooth or claw. As the wrench is turned, the tooth prevents the head from slipping out of place, allowing the user to adjust the part quickly and efficiently. Due to the fact that it is available in a range of different sizes that can be used to adjust parts under varying circumferences.
