What is an Allen key and how is it used?
An Allen key, also known as a hex key, is a tool used to drive bolts and screws with a hexagonal socket in the head. It is a simple, yet versatile tool that consists of a long, flat handle with a hexagonal tip at one end. The hexagonal tip is inserted into the socket of the bolt or screw, and the handle is turned to tighten or loosen the fastener. Allen keys are commonly used in a variety of applications, including construction, automotive repair, and furniture assembly.
The use of an Allen key provides a number of advantages over other types of tools. For example, the hexagonal socket provides a secure drive system, which helps to prevent the tool from slipping out of the socket and damaging the surrounding material. Additionally, the long handle of the Allen key provides leverage, making it easier to apply the necessary torque to tighten or loosen the fastener. Overall, the Allen key is a reliable and efficient tool that is an essential part of many toolboxes and workshops.
Who invented the Allen key and when was it patented?
The Allen key was invented by William G. Allen, an American businessman and inventor, in the early 20th century. Allen was the owner of the Allen Manufacturing Company, a firm that produced hexagonal socket screws and other fasteners. In 1909, Allen was granted a patent for his design of a hexagonal socket screw, which featured a recessed hexagonal socket in the head of the screw. The patent also covered the design of a tool, later known as the Allen key, which was used to drive the screw.
The invention of the Allen key and the hexagonal socket screw revolutionized the way that parts were assembled and disassembled. Prior to the introduction of the Allen key, screws and bolts were typically driven using flathead or Phillips-head drivers, which were prone to slipping out of the socket and damaging the surrounding material. The Allen key and hexagonal socket screw provided a more secure and efficient drive system, which quickly became popular in a variety of industries. Today, the Allen key is a ubiquitous tool that is used in many different applications around the world.
What are the different types of Allen keys available?
There are several different types of Allen keys available, each with its own unique characteristics and applications. The most common type of Allen key is the standard hex key, which features a hexagonal tip and a long, flat handle. There are also ball-end hex keys, which feature a ball-shaped tip that allows for greater flexibility and reach. Additionally, there are long-arm hex keys, which feature an extended handle and are used for applications where extra leverage is required.
In addition to these types of Allen keys, there are also a number of specialty keys available, such as Torx keys and security keys. Torx keys feature a star-shaped tip and are used to drive screws with a Torx socket. Security keys, on the other hand, feature a unique tip that is designed to fit a specific type of socket, and are used to prevent tampering or unauthorized access. Overall, the type of Allen key used will depend on the specific application and the type of fastener being driven.
