1-14 x 1 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.

Fine-thread and longer square-head sizes are a hard-to-find lane, so exact thread and length identification matters before sourcing. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
