Typically, set screws are intended for use in fastening down (setting) parts or components that would otherwise be able to move or slide around relative to one another . The set screw works by passing through a threaded hole in one component and butting up tightly against the surface of a second part on the rear side. Grade 10.9 bolts: As these bolts are most often used in the automotive industry, they are also referred to as 'car bolts'. They are made of boron or carbon steel and have high tensile strength (1040 MPa) .
