wrenches

A wrench (or spanner) is a tool used to grip, turn, or apply torque to nuts, bolts, and other fasteners. It typically has a handle and a jaw or opening that fits around the fastener. Different types include adjustable wrenches, which can be sized for various fasteners, and fixed types like box or open-end wrenches. Wrenches are essential in assembling, repairing, and maintaining machinery, plumbing, and automotive work, providing leverage to tighten or loosen fasteners securely and efficiently.
