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

These inch size set screws are vented to allow fluid and gas to pass through.

Made from 18-8 stainless steel, these set screws are chemical resistant. The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

Made from 316 stainless steel, these set screws have excellent chemical resistance and can be used in saltwater environments. The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

These chemical-resistant 18-8 stainless steel screws have an extra-soft nylon tip, which minimizes the damage that can occur from metal-on-metal contact. Use them on soft surfaces such as aluminum.

These set screws have a tip that is harder than nylon and silver to provide a secure hold on hard surfaces. The body is 18-8 stainless steel for good chemical resistance.

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

Also known as dog-point set screws, these metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. Made of 18-8 stainless steel, they have good chemical resistance.

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

These metric 18-8 stainless steel set screws are chemical resistant. A pointed tip wedges into the contact surface for a secure hold on soft materials such as brass.

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

Stainless steel set screws have excellent corrosion resistance in most environments.

Stainless steel set screws have excellent corrosion resistance in most environments.

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

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.

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 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.

These 18-8 stainless steel 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.

Tighten these screws by turning them to the left; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, these screws have good chemical resistance and 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.

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.

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.

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

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

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

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.

With a hex socket at the tip as well as the head, you can fasten these shoulder screws from the tip when the head cannot be reached.

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

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

These metric 316 stainless steel shoulder screws are more corrosion resistant than 18-8 stainless steel shoulder screws. They also have excellent resistance to chemicals and salt water.

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

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

Shoulder screws have a cylindrical shoulder under the head that allows parts to rotate around or slide along its length. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.
