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.

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.

Flat Head Screws

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

Set Screws

Unlike screws that hold materials together with threads, set screws exert pressure at the tip to hold objects in place.
