π What is an Allen Wrench?
An Allen wrench, also known as a hex key, is a tool used to drive bolts and screws that have a hexagonal socket in the head. These tools are simple in design, usually L-shaped, and come in various sizes to fit different socket dimensions. They are commonly used in furniture assembly, bicycle repair, and machine maintenance due to their efficiency and accessibility in tight spaces.
π A Brief History
While precise origins are debated, the hexagonal socket screw drive and corresponding wrenches became commercially available in the early 20th century. W.G. Allen is often credited with popularizing the design, hence the name 'Allen' wrench. These tools gained prominence due to their simplicity, low manufacturing cost, and effectiveness in applications requiring high torque.
