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.

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.

Carriage Bolts

Carriage bolts have a smooth, rounded head for a finished look. The neck shape keeps them from turning when tightening a nut.

Set Screws

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

Screw Assortments

T-Slot Bolts

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.
