Brass 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.

A286 stainless steel screws have comparable strength to alloy steel with 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.

Create a decorative appearance on your finished product—the head of these screws is painted.

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.

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.

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 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 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.

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

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

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

Lower strength than alloy steel, use these screws for light duty fastening.

Prevent unwanted removal, leaks, and contamination with these sealing Torx screws.

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

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

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

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

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

These 18-8 stainless steel set screws are chemical resistant. They have a nylon locking patch that grips threads to resist loosening.

Made from black-oxide alloy steel, these set screws resist corrosion in dry environments. They dig into hard surfaces for a secure hold and have serrations on the cup edge that grip the material surface to resist loosening.

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.

These nylon set screws are chemical resistant, lightweight, and nonconductive. 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.

These set screws have a softer tip than brass-tip set screws to minimize surface damage. Use them on hard surfaces.

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

These alloy steel set screws have a pointed tip that wedges into the contact surface for a secure hold on soft materials such as brass.

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

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

Also known as jam set screws, these lock other screws in place, hold pins, and adjust spring tension. A black-oxide finish provides corrosion resistance in dry environments.

Made from 18-8 stainless steel, these inch-sized shoulder screws have good chemical resistance.

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.

Titanium shoulder screws have a high strength-to-weight ratio and are more resistant to acids and salt water than nickel shoulder screws.

Screw these shoulders onto a stud.

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

These slotted screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

These shoulder screws come with a traceable lot number and material test report.

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

Comparable to Grade 8 steel, these screws are the strongest precision shoulder screws we offer.
