Fasteners such as socket head cap screws, also known as Allen Head screws, have sockets within their heads so that Allen wrench could secure the screw. A socket head capscrew, also known as socket cap screw, socket screw, or allen bolt is a screw characterized by its head having a hexagonal socket. Allen or hex socket is the primary driver used and is to be torqued using an Allen wrench, also called a hex key. Allen socket screws are often seen as advantageous over the normal Philip’s head. Allen screw head has six pressure points while the other one has only four. With more pressure points, it is easier to grip the screw making Allen screws preferable. 

Capscrews fasten machines together with the help of a nut. When tightened, capscrews fastened different parts together using the tensile load that’s created when the screws are tightened. This is because this action creates stretching of the screws.

Unlike the stainless steel allen socket-head capscrew, this one has less protection against corrosion although it’s durable just the same.
