5/8-11 x 3/4 Cup Point Square Head Set Screw gives maintenance crews a wrench-driven cup point fastener for machinery that still calls out square-head hardware. The cup point creates localized contact with the mating surface, while the external flats give the installer a direct wrenching surface.

Vibrating screens and related material-handling equipment can require this older square-head pattern for maintenance consistency.

For older machinery and uncommon set screw callouts, Cold Headers helps match the requested diameter, length, head style, and point configuration. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
