Where a bill of material calls for a wrench-driven cup point screw, the 3/8-16 x 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.

Production fixtures and adjustment stops sometimes retain square-head set screws for fast visual confirmation and wrench access.

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.
