3/4-10 x 2 1/4 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.

Industrial controls with exposed mechanical adjustments can use square-head set screws where a protruding wrench head is intentionally specified.

When a machine still calls out square-head hardware, the exact-size listing helps avoid replacing a legacy part with the wrong drive style. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
