1/2-13 x 7/8 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.

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

Fine-thread and longer square-head sizes are a hard-to-find lane, so exact thread and length identification matters before sourcing. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
