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

Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

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

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

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

Skip the washer—these metric stainless steel nuts have a flange that does the same job, spreading pressure across its surface for a strong hold.

These metric coupling nuts have good chemical resistance.

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

Low-profile cap nuts are about 20% shorter than standard cap nuts for use in low-profile applications.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.

Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench.

A nylon insert grips threads to resist loosening.

Cap nuts cover and protect threads while providing a finished appearance.
