7/16-14 x 1 1/2 Cup Point Square Head Set Screw is a square-drive, cup-point set screw for assemblies where the head itself provides the wrenching surface. The square flats also make the part recognizable on older assemblies that were designed before headless hex-socket set screws became common.

Plant maintenance programs that are standardized on square-head set screws can keep one recognizable drive style across multiple machines. Plain carbon steel is not selected for corrosion resistance; keep parts oiled in service, or ask about stainless square-head options as a non-catalog request.

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.
