Use the 1/2-13 x 1/2 Cup Point Square Head Set Screw where drawings specify a protruding square head and cup point rather than a headless style. It is a practical choice when top-side wrench access is available and a protruding head is acceptable in the design.
Legacy machine rebuilds often need the same square-head geometry to match existing drawings and replacement records. Because a square head protrudes and rotates with the shaft, exposed rotating assemblies near personnel may call for a guarded headless set screw instead.
Cold Headers can help confirm pricing and availability for exact-size square-head cup point set screws without making unsupported availability promises. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
