The standard for high-strength fastening.

Cleaned and double bagged in an ISO Class 5 (Fed. Std. Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.

Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They are comparable in strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

Plastic screws are chemical and oil resistant, nonconductive, and lightweight.

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws.

More corrosion resistant than stainless steel screws, nickel alloy screws have excellent resistance to salt water and some acids.

Nearly as strong as steel, these stainless steel screws won’t rust in outdoor, washdown, and other corrosive environments. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

Made from alloy steel, these screws are nearly twice as strong as stainless steel low-profile screws. With a head height one-third the size of a standard socket head, they fit in the tightest spaces.

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

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

The nylon patch bonded to the threads of these socket head screws adds friction to keep vibration from loosening them, while their O-ring prevents leaks and seals out contaminants.

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

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

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

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

These metric alloy steel 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.

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.

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 18-8 stainless steel, these metric 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.

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