Screws and Bolts

Slotted Rounded Head Screws

Phillips Rounded Head Screws

Torx Rounded Head Screws

A Torx drive has more points of contact than other drives—allowing you to tighten the screw without damaging the recess.

Hex Drive Rounded Head Screws

Sealing Rounded Head Screws

A rubber O-ring prevents leaks and seals out contaminants.

Vibration-Resistant Rounded Head Screws

Prevent screws from loosening due to vibration. Includes screws with thread locker, screws with lock washers, and screws that are wire lockable.

Flat Head Screws

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

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.

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.

Ball Screws and Nuts

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement.
