With a tensile strength of 180,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and more than two and a half times stronger than stainless steel screws with split lock washer. The split lock washer helps to resist vibration.

Stainless steel screws have excellent corrosion resistance in most environments. Wire these screws together for more vibration resistance than other types of socket head screws.

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

Seal out contaminants and prevent leaks—a rubber O-ring under the head prevents leaks and seals out contaminants.

Nonconductive and softer than brass, the nylon tip reduces vibration and eliminates damage from metal touching metal.

A freely rotating washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

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

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

Closely spaced threads on these screws fit in holes with a fine pitch. They're not compatible with standard metric threads.

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

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

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

With a tamper-resistant hex drive (also known as a pin-in hex drive), these metric screws are difficult to remove without special tools.

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

316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They may be mildly magnetic.

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

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

Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

With a flange comparable in size to a washer, these metric screws distribute 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.

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.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

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

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

To vent fluid and gas trapped under the screw, these metric screws are drilled through the shaft. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Turn these metric screws to the left to tighten; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. They're available in metric sizes.
