About Set Screws

Cup-Point Set Screws

Cup point set screws have a thin edge that digs into the contact surface for a secure hold on a wide range of surfaces.

Nonmarring Set Screws

Make frequent adjustments with minimal surface damage. Choose from flat-, oval-, and soft-tip set screws.

Extended-Tip Set Screws

Also known as dog-point set screws, these set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned.

High-Hold Cone-Point Set Screws

For a secure hold on soft materials such as brass, the pointed tip wedges into the contact surface.

Easy-Adjust Ball-Point Set Screws

A ball bearing tip rolls to allow for slight adjustments without loosening the screw.

Hollow-Lock Set Screws

Also known as jam screws, these lock other screws in place, hold pins, and adjust spring tension.

Swivel-Tip Set Screws for Angled Surfaces

The tip swivels and tilts in all directions to apply uniform pressure to angled and uneven surfaces.

Spring Plungers

A spring projects the nose to apply accurate, consistent pressure for positioning, indexing, and ejecting parts.
