What is a Hex Key With Hole?

A hex key with hole, also known as an Allen key or hex wrench, is a tool used to drive screws, bolts, and other fasteners. It has a hexagonal head at one end and a hole at the other end that fits over a shaft or bolt head. The hexagonal head is designed to fit into a hexagonal-shaped recess in the fastener head, allowing the user to turn the fastener with a wrench.

Features of Hex Key With Hole

Hex keys come in a variety of sizes and are made from a variety of materials, including steel, brass, and aluminum. They are typically used in areas where a standard screwdriver is not suitable, such as in tight spaces or areas with limited access. Hex keys are also used in the assembly and disassembly of certain equipment and machines.


Hex keys are easy to use and can be used in a variety of applications. They are also more secure than standard screwdrivers, as the hexagonal shape is designed to prevent the fastener from slipping out of the recess. Hex keys also provide more leverage than a standard screwdriver, allowing the user to apply more torque when turning the fastener.


Hex keys require a greater level of precision than other tools, as the hexagonal shape must match the recess in the fastener head. They are also more expensive than other tools, such as screwdrivers.
