More corrosion resistant than 18-8 stainless steel screws, these pan head screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

These steel pan head screws are coated for corrosion resistance.

Nylon pan head screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Our most corrosion-resistant screws, these titanium pan head screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material. Screws may be mildly magnetic.

A zinc plating provides mild corrosion resistance.

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

These screws have a Torx or Torx-Plus drive for more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from brass, these screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

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

Nylon screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Made from nylon, these screws are chemical and oil resistant, nonconductive, and lightweight.

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

18-8 stainless steel pan head screws have good chemical resistance and may be mildly magnetic.

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

Stainless steel screws have excellent corrosion resistance in most environments.

Stainless steel screws have excellent corrosion resistance in most environments.

A zinc plating provides mild corrosion resistance.

These screws have a tall, domed head that provides a finished appearance. They're zinc plated to resist corrosion in wet environments.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

These aluminum screws are lightweight and resist corrosion in wet environments. They have a flange that is wider and thicker than our other flanged screws, so they distribute pressure the best.

Comparable in diameter to a washer, the flange on these screws distributes pressure better than standard flanged screws. Made from 316 stainless steel, they have excellent resistance to chemicals and salt water. Screws may be mildly magnetic.

To prevent unwanted removal, these screws have a tamper-resistant Torx drive—also known as a pin-in Torx drive—that makes them difficult to unscrew without special tools. An O-ring under the head blocks leaks and seals out dust and dirt.

A tamper-resistant drilled spanner drive makes these screws difficult to remove without special tools. They're 18-8 stainless steel for good chemical resistance and may be mildly magnetic.

Difficult to remove without special tools, these screws have three grooves.

A zinc plating provides mild corrosion resistance.

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

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. All have a washer with sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

The washer on these screws has sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. A curved washer protects delicate surfaces while providing constant tension. Also known as Square Cone Sems screws, the washer rotates freely but is permanently attached.

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

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

These steel screws have a zinc plating for mild corrosion resistance.

Our most corrosion resistant screws, titanium screws withstand salt water, acids, and chemicals.

These screws have a decorative, domed head that sits above the surface when installed.

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

Polycarbonate screws resist breaking in high impact applications better than other plastic screws. All are chemical and oil resistant, nonconductive, and lightweight.

A zinc plating provides mild corrosion resistance.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws.

Prevent unwanted removal, leaks, and contamination with these sealing Torx screws.

A tamper-resistant hex drive (also known as pin-in hex drive) makes these screws difficult to remove without special tools.

Stainless steel screws have excellent corrosion resistance in most environments.
