Screws and Bolts

Hex Head Screws

Hex head screws are easy to install with a wrench for a secure hold. Use them with a nut or in tapped holes.

Socket Head Screws

With a deeper drive than flat and rounded head screws, socket head screws withstand more torque for a tighter hold. Install in a counterbored hole or above the surface.

Vented Cup-Point Set Screws

Vented to allow fluid and gas to pass through.

Vented Flat Head Screws

These screws are drilled through the shaft to vent fluid and gases trapped under the screw.

Rounded Head Screws

A domed head sits above the surface of your material. Includes screws such as pan, button, binding, and truss head screws.
