Closely spaced metric threads prevent these nuts from loosening due to vibration. About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to Class 10.9 nuts.

These metric nuts have good chemical resistance and may be mildly magnetic.

Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.

These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts—use them around chemicals and salt water when space is limited.

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 metric locknuts have good chemical resistance.

Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.

Secure these metric nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. Often referred to as castle nuts.

When installed, the steel insert in these metric locknuts grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration.

These metric coupling nuts have good chemical resistance.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends.
