Choose these metric screws for fastening most machinery and equipment. With a flange distributing pressure where the screw meets the surface, there is no need for a separate washer.

These metric screws are at least 25% stronger than medium-strength steel screws. Use them in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The flange distributes pressure where the screw meets the surface, so there's no need for a washer.

Comparable in strength to Grade 9 screws, these are about 20% stronger than high-strength steel screws and often used in heavy duty applications, such as stamping and earth-moving equipment. The flange eliminates the need for a washer.

For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

These screws are chemical and oil resistant, nonconductive, and lightweight. The flange eliminates the need for a washer, distributing pressure where the screw meets the surface.

These metric screws are suitable for fastening most machinery and equipment. They have a serrated flange that helps prevent loosening from vibration.

About 20% stronger than medium-strength steel screws, these Grade 8 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Serrations under the flange provide mild vibration resistance.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. A serrated flange provides mild vibration resistance.

Made from alloy steel, these 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.

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.

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.

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. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Made from aluminum, these metric screws are lightweight and resist corrosion in wet environments. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. A curved washer protects delicate surfaces while providing constant tension. Also known as Square Cone Sems screws, the washer rotates freely but is permanently attached.

Made from stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. The washer has sharp internal teeth that dig into surfaces to resist large amounts of vibration while the smooth outside edge provides a finished look. Also known as Sems screws, the washer rotates freely but is permanently attached.

The flat washer distributes holding pressure and protects delicate surfaces from damage while the split lock washer adds tension to prevent loosening from small amounts of vibration.

Made from stainless steel, these screws have good chemical resistance and may be mildly magnetic. All have a washer with sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

These metric screws have a washer with sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.

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

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

Good for high-strength fastening, these screws are made from alloy steel comparable in strength to Grade 9 steel. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.

Cutting their own pilot hole and threads as you fasten them into material, these metric screws have a drilling tip.

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation.

These steel screws have a head encapsulated by 18-8 stainless steel.

Able to penetrate overlapping sheets, these screws have a secure hold in wood.

The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections.

A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw.

With a low-profile rounded head that’s flanged to sit flush for a finished appearance, these screws press threads into wood on cabinets, trim, molding, and light duty framing.

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

Cutting wings under the head allow plastic to expand and contract without cracking. A washer made from aluminum and rubber bonded to steel adds a watertight seal.
