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.

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.

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.

Shoulder Screws

A cylindrical shoulder under the head allows parts to rotate around and slide along its length, so these screws are often used to guide and align components.
