Question: Why do some technicians use allen keys instead of self-tapping screws to fasten joints?
Allen keys, also known as hex keys, are tools used to drive bolts and screws with hexagonal sockets. They have six driver points, making them easier to work with and less prone to stripping1. On the other hand, self-tapping screws are screws that can tap their own hole as they are driven into the material. They are available in a wide range of tip and thread patterns and can be used with almost any possible screw head design2. Technicians may choose to use Allen keys instead of self-tapping screws for several reasons. One reason is that Allen keys provide a more secure grip and are less likely to slip or strip the fastener. Additionally, using the correct size hex key is critical, as using one that is too large may damage the fastener or too.
