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.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for 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.

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

A freely rotating washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

The nonmarring brass tip is electrically conductive and harder than nylon, but soft enough to conform to most surfaces and reduce damage from metal-on-metal contact.

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

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

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.

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

As strong as alloy steel and about 40% lighter, these metric titanium screws are known for their high strength-to-weight ratio. They stand up to salt water, acids, and chemicals.

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.

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.

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.

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.

With a flange comparable in size to a washer, these metric screws distribute 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. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

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

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 screws are drilled through the shaft to vent fluids and gases trapped under the screw. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Comparable to Class 12.9 steel.

With threads the same diameter as the shoulder, these inch-sized screws can handle heavy loads. They’re comparable to Grade 8 steel.

These shoulder screws come with a traceable lot number and material test report. Similar in strength to Grade 8 steel.

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.
