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.

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.

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. Wire these screws together for more vibration resistance than other types of socket head screws.

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

No need for separate bits—these screws lock directly onto square-drive socket wrenches, reducing the risk of dropping parts during installation.

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

Seal out contaminants and prevent leaks—a rubber O-ring under the head prevents leaks and seals out contaminants.

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.

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

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 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.

These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

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.

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

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.

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

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.

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

Known for their high strength-to-weight ratio, these titanium screws are as strong as alloy steel and about 40% lighter. 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.

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.

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.

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.

Turn these metric screws to the left to tighten; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

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.

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 in strength to Grade 8 steel. These screws have inch thread sizes.

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

Use these screws in thin materials; they have a shorter threaded portion than our standard shoulder screws. They’re comparable in strength to Grade 8 steel.

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

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

Nickel alloy shoulder screws are more resistant to acids and salt water than stainless steel shoulder screws.

One-third the weight of steel, aluminum shoulder screws are lightweight and have good corrosion resistance.

A locking element on the threads adds friction to resist loosening. Comparable to Grade 8 steel, these alloy steel shoulder screws are the strongest we offer.

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