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

More corrosion resistant than 18-8 stainless steel screws, these button head 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.

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.

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

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Torx and Torx-Plus drives have more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

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.

Made from A286 stainless steel, these metric screws provide the strength of alloy steel and the corrosion and chemical resistance of 18-8 stainless steel. They have a Torx drive that has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

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

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.

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.

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.

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.

Made from 18-8 stainless steel, these 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.

These 18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

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.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

Made from 18-8 stainless steel, these metric button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant hex drive (also known as a pin-in hex drive) makes them difficult to remove without special tools.

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

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.
