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

Insert these plugs into the drive socket to block debris and provide a finished look.

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

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

These steel pan head screws are coated for corrosion resistance.

Made to Japanese Industrial Standards, these screws have narrower and shorter heads than standard Phillips pan head screws.

A zinc plating provides mild corrosion resistance.

Install these metric pan head screws for a low-profile, finished look—no countersink required.

A zinc plating provides mild corrosion resistance.

A zinc plating provides mild corrosion resistance.

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

These screws have a Torx or Torx-Plus drive for 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.

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.

These metric screws have a washer with sharp internal teeth that dig into surfaces to resist large amounts of vibration. The smooth outside edge of the washer provides a finished look. 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.

As you tighten these metric screws, the split lock washer flattens to add tension and prevent loosening from small amounts of vibration. Also known as Sems screws, the washer rotates freely but is permanently attached.

Difficult to remove without special tools, these screws have three grooves.

Choose these metric screws for high-strength fastening. Often used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems, these screws are at least 25% stronger than medium-strength steel screws.

When clearance for a wrench is limited, these screws have a Phillips drive so you can install them with a screwdriver. They are used for high-strength fastening.

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. For use in high-strength fastening applications.

Choose these metric screws for fastening most machinery and equipment. They are twice as strong as low-strength steel screws.

These screws are made to stringent Army-Navy specifications that ensure performance and reliability. They're comparable in strength to Grade 5 steel screws.

These metric screws help prevent counterclockwise-moving parts from loosening. Use them for medium-strength fastening.

These screws are the strongest we offer. They are about 20% stronger than high-strength steel screws and are often used in heavy duty applications such as stamping and earth-moving equipment.

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.

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.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Serrations under the flange provide mild vibration resistance.

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.

Place a cotter pin through the hole in the shank to keep a nut from loosening. These screws have a stronger hold than screws with thread lockers or lock washers.

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. They are over 50% stronger than stainless steel thread-locking screws. For vibration resistance, they have a thread locker bonded to the threads.
