1-14 x 2 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.

This family includes uncommon square-head lengths, making the exact size useful for replacement searches and legacy drawings. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
