About Rounded Head Screws

18-8 Stainless Steel Button Head Hex Drive Screws

These screws have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless
Steel Button Head Hex Drive Screws

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water.

Alloy Steel Button Head Hex Drive Screws

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

Brass Button Head Hex Drive Screws

Brass screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Titanium Button Head Hex Drive Screws

Known for their high strength-to-weight ratio, these titanium screws are as strong as alloy steel and about 40% lighter. They stand up to salt water, acids, and chemicals.

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.

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.

Flanged Rounded Head Screws

The flange distributes pressure across a wider surface, eliminating the need for a separate washer.

Tamper-Resistant Rounded Head Screws

Difficult to remove without special tools, use these screws in public spaces to reduce the risk of theft and tampering.

Left-Hand Threaded Rounded Head Screws

Tighten these screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion.

Vented Rounded Head Screws

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

Rounded Head Screw Assortments

These screws are also known as pan head and button head screws.
