What Are Stainless Steel Cup Point Set Screws?

Stainless Steel Cup Point Set Screws are headless threaded fasteners with an internal hex drive.

The cup point design features a concave tip that creates a strong gripping effect when tightened against a mating surface.

The sharp edge of the cup point digs into the contact surface, providing:

✔ Strong holding force
✔ Reliable positioning
✔ Resistance to loosening
✔ Compact installation design
✔ Space-saving fastening solution

Unlike standard bolts, set screws are designed primarily for securing components in position rather than clamping multiple parts together.
