What is a Crows Foot Wrench and How Does It Work?

A crows foot wrench, also known as a crowfoot spanner, is a specialized tool used in mechanical applications. It is an extension of a socket wrench and is designed to provide access to fasteners in tight or hard-to-reach spaces where a regular socket wrench cannot fit.

The crows foot wrench is named after its resemblance to a crow’s foot, with multiple prongs extending from a base. These prongs can be attached to a socket or drive tool, allowing the user to apply torque to fasteners at different angles.

Design and Construction

A crows foot wrench is typically made of high-strength steel, ensuring durability and resistance to wear and tear. It consists of a base with a square drive or hexagonal opening, on which the prongs are attached.

The prongs of the wrench can vary in number and size, depending on the specific application. They are usually thin and flat, allowing them to fit into tight spaces. The prongs may be open-ended or closed, depending on the type of fastener they are designed to work with.

Using a Crows Foot Wrench

To use a crows foot wrench, you need to attach it to a socket or drive tool. Simply insert the drive tool into the square drive or hexagonal opening on the base of the wrench and secure it in place. The prongs of the wrench should align with the fastener you are working on.

Once the wrench is attached, you can apply torque to the fastener by turning the drive tool. The prongs of the wrench will grip the fastener, allowing you to loosen or tighten it. The crows foot wrench allows for access to fasteners in tight spaces, such as those located near walls or other obstructions.
