Closely spaced metric threads prevent loosening from vibration. These Class 10 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

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

These locknuts have good chemical resistance.

Grip metric bolts more securely than nylon-insert flange locknuts—the irregularly shaped threads on these locknuts hold extra tight. They resist vibration and sudden shocks, even after multiple uses.

Strong enough for use in most machinery and equipment, these medium-strength metric nuts have serrations on the underside of the flange. The serrations prevent the nuts from loosening in applications with mild vibration.

Metric 18-8 stainless steel is also known as A2 stainless steel. These flange locknuts have good chemical resistance and may be mildly magnetic.

To resist loosening from vibration, these metric locknuts have a nylon patch bonded to their threads that adds friction. They have good chemical resistance and may be mildly magnetic because they’re stainless steel.

The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes.

The teeth on these washers bite further into the screw head and joint than standard external-tooth washers to provide a stronger hold.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. Use with metric fasteners that have small heads, such as fillister and cheese head screws.

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.
