Socket set screws, also known as grub screws, are blind (headless) fasteners with an internal hex drive. Grub screws are used in a tapped hole and tightened to hold an exterior object in place within or against another object, via friction between the point or end of the screw and the material that is being fastened. Socket set screws will run flush with the installation surface. They are often plugged after installation for a hidden fastener look. Set screws are commonly used in applications where a flat surface is important, such as handles, grips, surfboard fins, and furniture or machine assembly. Because a flush surface is important on complex machines, set screws are also commonly used in gears, pulleys, and wheels in machines with moving parts. The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compression or clamping force through the bottom tip that projects through the hole. Cone point set screws are most often utilized in permanent settings, though they can also be used as a pivot or hanger.
