3/4-10 x 6 Cup Point Square Head Set Screw is a case hardened carbon steel set screw built around an external square head instead of a recessed drive. The open square head is useful when a standard wrench is preferred and the drive must stay visible during adjustment.
Packing gland and follower adjustments are typical service points where wrench-driven set screws are still specified. Where a protruding head will not clear the design, Cup Point Slotted Headless Set Screws provide a screwdriver-driven headless alternative.
This family includes uncommon square-head lengths, making the exact size useful for replacement searches and legacy drawings. The thread, length, across-flats size, head height, and cup point diameter should be checked against the print before purchase.
