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.

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.

Set Screws

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

Tapping, Wood, and Drywall Screws

While other screws and bolts require holes with threads, tapping screws create their own threads.

Captive Panel Screws

Secure panels and enclosures while allowing access. Screws become part of the panel when installed, so they won't fall out and get lost.

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.

Other Metric Socket Screws

Screw Assortments

Reference Charts

Includes charts that list specifications and tightening guidelines for socket screws as well as charts that provide decimal equivalents and drill sizes.
