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

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.

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.

A high-strength alternative to blind rivets, use these screws when only one side of the material is accessible.

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.

The Torx or Torx-Plus drive on these metric screws have more points of contact than other drives, allowing you to tighten them without damaging the recess.

Turn these metric screws by hand using the hex head, or tighten them with a wrench for extra torque. With an extended tip that locks into a mating hole or slot—sometimes known as a dog point—they are often used to align and secure parts such as gears and pulley wheels.
