Screws and Bolts

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.

Rounded Head Screws

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

Flat Head Screws

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