What type of tool do wrenches belong to?

Wrenches are classified as turning or leverage tools because they are specifically designed to grip and turn fasteners such as nuts and bolts. The design of a wrench provides the necessary leverage to apply torque, allowing the user to tighten or loosen fasteners effectively. The mechanics of using a wrench involve applying a force at a distance from the pivot point (the bolt or nut), making it an essential tool for tasks that require turning motion to secure or release fittings.

These tools are fundamental in various applications, from mechanical work to household repairs, highlighting their versatility and importance in both professional and DIY contexts. The classification focuses on their primary function—leveraging movement to achieve tightness or looseness in hardware, which distinguishes them from tools meant for cutting, measuring, or otherwise fastening materials.
