Socket Set Screws are used in installations where a flush application surface is important. Set screws are ideal for this type of application because they are headless (blind) fasteners, which means that nothing will protrude above the application surface. Blind fasteners also add another layer of security to a tamper proof assembly. Because they run flush with or even sometimes below the application surface they are less vulnerable to gripping devices such as pliers. Set screws are commonly used in pulleys, tracks, manufacturing, surfboard fins, handles and grips.
