What is Allen Key Screw?

An Allen key screw is a type of fastener that has a hexagonal head with an internal socket drive. This type of screw requires an Allen wrench (also known as a hex key) to be inserted into the socket drive in order to tighten or loosen it. The advantage of this type of screw is that it can be installed or removed without needing to drill any extra holes. Moreover, because the head is recessed below the surface, it gives a neat and tidy finish to projects where aesthetics matter.

These types of screws are often used in projects where there is limited space, such as furniture assembly, car parts, and electronics repairs. They also come in handy when working on construction projects as they provide strong yet secure fastening power without having to put extra effort into drilling out large holes for traditional screws. Other uses for these types include attaching hinges, door handles/knobs, and even eyeglass frames!


Overall, understanding what an Allen key screw is and its various uses can help ensure that your next project goes smoothly. With this knowledge, you now know exactly which type of fastener will fit your needs best and get your job done correctly the first time around! Whether it’s repairing electronics or assembling furniture pieces, having the right tools makes all the difference!
