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.

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

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 flange under the head distributes holding pressure and reduces the risk of crushing thin metal.

One-third the weight of steel, these aluminum nuts are corrosion resistant in wet environments and nonmagnetic.

Made from medium-strength steel with a nylon insert, these Class 8 metric locknuts are strong enough to use on most machinery and equipment that’s prone to vibration and temperature changes.

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

These nuts are about 25% stronger than medium-strength steel cap nuts.

Wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.

USS washers generally have a larger ID and OD than SAE washers.
