3/4-16 x 3/4 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.

Sprocket hubs, drive collars, and shaft-mounted handles are natural locations for a cup point that bears against a mating surface. For square-head specifications that call for half dog, full dog, flat, cone, or oval points, review the broader Square Head Set Screws family.

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.
