Where a bill of material calls for a wrench-driven cup point screw, the 7/16-14 x 3 1/2 Cup Point Square Head Set Screw keeps the size and geometry explicit. It is a practical choice when top-side wrench access is available and a protruding head is acceptable in the design.

Older production lines and repairable plant equipment often keep these fasteners because the square head is visible and tool-friendly.

Cold Headers keeps the catalog language focused on size, geometry, material, and verified dimensions so buyers can compare parts cleanly. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
