3/8-24 x 3 1/2 Cup Point Square Head Set Screw is a plain-finish carbon steel fastener for square-head set screw specifications. The square flats also make the part recognizable on older assemblies that were designed before headless hex-socket set screws became common.

Mill and grinder adjustments use this style where rugged wrench access is part of the original machine design.

For older machinery and uncommon set screw callouts, Cold Headers helps match the requested diameter, length, head style, and point configuration. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
