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. The number 12.9 indicates the tensile strength of the steel in units of hundreds of megapascals (MPa) . In this case, the "12" represents a tensile strength of approximately 1200 MPa. The "9" represents the ratio of the yield strength to the tensile strength.
