Knurled Cup Point Grub Screw

Cup point grub screw with a knurled body for tool-free hand tightening. The serrated outer surface allows manual adjustment in fixtures, jigs, and quick-change tooling setups where a hex key is not accessible or frequent re-positioning is required.

Designed for production environments where frequent manual adjustments are needed, these screws combine the secure holding power of a cup point with the convenience of finger-tightened installation — ideal for jig fixtures, educational equipment, and light-duty assemblies.

Hand Tightened M4 – M16 MS Black / SS304 Cup Point Tool-Free
