Understanding Wrenches: Types and Uses

A wrench is a tool used to tighten or loosen bolts and nuts, typically by applying torque. It consists of a metal shaft with a handle on one end and a socket or wrenching head on the other end. The socket or wrenching head is designed to fit over the bolt or nut and apply pressure to it, either by turning the handle or by using a ratchet mechanism.
Wrenches come in various sizes and shapes, each designed for specific tasks. Some common types of wrenches include:
Open-end wrench: This is the most basic type of wrench, with a flat, open end that can be used to turn bolts and nuts in any direction.
Box-end wrench: This type of wrench has a closed end that is designed to fit into the socket of a bolt or nut, providing more torque than an open-end wrench.
Combination wrench: This type of wrench has both open and box-end ends, allowing for versatility when working with different types of fasteners.
Ratchet wrench: This type of wrench uses a ratchet mechanism to allow for easy tightening or loosening of bolts and nuts without having to remove the wrench from the socket.
Torque wrench: This type of wrench is designed to apply a specific amount of torque to a bolt or nut, ensuring that it is tightened to the correct specification.
Adjustable wrench: This type of wrench has a movable jaw that can be adjusted to fit different sizes of bolts and nuts, making it a versatile tool for a wide range of applications.
