About Set Screws

Cup-Point Set Screws

Install with a hex key.

Locking Cup-Point Set Screws

Designed with a locking element to resist loosening.

Flat-Tip Set Screws

Use these set screws for good contact on flat surfaces.

Soft-Tip Set Screws

The soft tip makes more points of contact than flat-tip and oval-tip set screws and conforms to textured and curved surfaces such as shafts.

Oval-Tip Set Screws

These set screws are often used in U-shaped and V-shaped grooves and on other sloped or angled surfaces.

Alloy Steel Cone-Point Set Screws

These alloy steel set screws have a pointed tip that wedges into the contact surface for a secure hold on soft materials such as brass.

Extended-Tip Set Screws

Thread-Locking Extended-Tip Set Screws

A nylon locking patch grips threads to resist loosening.

Extra-Long Extended-Tip Set Screws

The tip is twice as long as the tip on other extended-tip set screws for greater engagement in deep mating holes.
