More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Their ultra-low-profile lets them fit in the tightest spaces.

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

Stainless steel screws have excellent corrosion resistance in most environments. They have a split lock washer to create tension and resist loosening from vibration.

For use where sideways forces are a concern, these screws have a precisely measured unthreaded portion (grip) for a strong hold. Their flanged head distributes pressure where the screw meets the surface, so you don't need a washer.

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.

Fasten these screws inside a high-vacuum system without bringing in contaminants.

410 stainless steel is strong, wear resistant, and mildly chemical resistant.

These 316 stainless steel screws have excellent resistance to chemicals and salt water.

These 410 stainless steel screws are more corrosion resistant than ultra-corrosion-resistant coated steel screws.

18-8 stainless steel screws have good chemical resistance.

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

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

Choose these screws for their adherence to strict military standards for material and construction.

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

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

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.

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.

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.

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.

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.

These screws have metric thread sizes. They are 18-8 stainless steel for good chemical resistance.

For metric thread sizes with excellent resistance to chemicals and salt water, choose these 316 stainless steel shoulder screws.

Shoulder screws made of 17-4 PH stainless steel are nearly twice as strong as 18-8 stainless steel and have the same corrosion resistance. These screws have inch thread sizes.

These shoulder screws have good chemical resistance.

These shoulder screws are angled under the head to sit flush in countersunk holes.

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

Install and remove these metric shoulder screws by hand or with a hex key.

Made of 416 stainless steel, these shoulder screws are almost twice as strong as 18-8 stainless steel and have the same corrosion resistance.
