When using fasteners, you may come across some that look unfamiliar. These are fasteners designed for specific functions. One of them is a set screw. A set screw is a type of screw used to secure an object within another object. For example, a set screw is preferred for securing gear to a pulley, or fastening collars to shafts
.In most of the cases, set screws
do not have heads but only feature threaded shafts. This is the main reason why they are at times referred to as grub screws. But it is also possible to come across a set screw that also features a head.Set screws can be designed using any material such as steel, aluminum, titanium, and alloy steel that is used to make regular fasteners. Therefore, it is important to establish the best type of metal for your specific application. It is also crucial to factor the preferred screw tip depending on the expected results. For example, set screws can have cup points, flat point, cone point, domed points, and extended points.
