When dirt, oil, or frequent adjustment makes internal recesses less convenient, the 1/2-13 x 2 1/2 Cup Point Square Head Set Screw keeps the drive accessible. This pattern remains valuable on equipment where operators repeatedly loosen, reset, and tighten the same fastener.

Maintenance kits for legacy process equipment often include square-head cup point screws for follower, stop, and collar adjustments. Where a protruding head will not clear the design, Cup Point Slotted Headless Set Screws provide a screwdriver-driven headless alternative.

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.
