Set Screw Assortments

Cup Point with Serrations

Set screws exert pressure at the tip to hold objects in place. All have a cup point with a thin edge that digs into the contact surface for a secure hold. Length listed is the overall length.

Set screws with serrations on the cup edge grip the material surface to resist loosening.

Black-oxide alloy steel screws resist corrosion in dry environments.
