-
An Allen key, also known as an Allen wrench or hex key, is a small handheld tool that is primarily used to tighten or loosen screws and bolts with hexagonal sockets. The tool typically consists of a metal rod bent into an L-shape, with one end being a hexagonal shape that corresponds to the size of the fastener it is designed to work with. The opposite end of the key usually has a handle or grip for easy manual turninng.
The name "Allen key" originates from the manufacturing company, Allen Manufacturing Company, which first patented this type of wrench in the early 20th century. These keys were specifically designed to work with socket-head cap screws, which have a small, round indentation on the top of the bolt that resembles an "Allen" shape.
Allen keys are widely used in various industries, including engineering, construction, automotive, and furniture assembly. Their compact nature and ability to easily fit into tight spaces make them versatile and reliable tools for specific fastening applications.
The size of an Allen key is typically measured using the metric system, where the key’s dimensions correspond to the distance between opposing flat sides of a hexagon, often expressed in millimeters or inches. Common sizes include 2mm, 3mm, 4mm, 5mm, and 6mm, although larger or smaller sizes also exist depending on the specific application.
