3/8-24 x 2 1/2 Cup Point Square Head Set Screw fits older and current equipment that relies on square flats for set screw adjustment. The cup point creates localized contact with the mating surface, while the external flats give the installer a direct wrenching surface.

Conveyor drive pulleys and shaft-mounted components can use this pattern when a protruding drive head is acceptable.

Square-head cup point screws in fine thread and extended lengths can be difficult to source, so the SKU detail should be checked closely. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
