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.

Flat Head Screws

Flat Head Screws

Flat and oval head screws are angled under the head to fit in countersunk holes.

Rounded Head Screws

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

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.

12-Point Screws

12-Point Screws

The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.

Square Head Screws

Large flat sides make these screws easy to grip with a wrench and keep them from rotating in square holes.
