Use the 1-8 x 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.

Older production lines and repairable plant equipment often keep these fasteners because the square head is visible and tool-friendly. 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 supports industrial distributors, repair teams, and OEM buyers who need a precise thread, length, and point style without substituting geometry. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
