3/4-10 x 2 3/4 Cup Point Square Head Set Screw supports traditional wrench-driven set screw service in heavy mechanical assemblies. The open square head is useful when a standard wrench is preferred and the drive must stay visible during adjustment.

Common applications include crushers and aggregate equipment, where exposed wrench flats remain easy to reach during service. Plain carbon steel is not selected for corrosion resistance; keep parts oiled in service, or ask about stainless square-head options as a non-catalog request.

Use Cold Headers when the requirement is specific: square head, cup point, carbon steel, Class 2A thread, and the length shown on the drawing. The thread, length, across-flats size, head height, and cup point diameter should be checked against the print before purchase.
