Where a bill of material calls for a wrench-driven cup point screw, the 1-8 x 3/4 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 is a practical sourcing contact when a print still calls for square-head cup point hardware in a specific size. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
