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

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

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

Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.

These locknuts have good chemical resistance.

Stainless steel locknuts have excellent corrosion resistance in most environments.

About half the height and 10% wider than standard flex-top locknuts, use these locknuts in low-clearance applications or jam one against an extra-wide hex nut to hold it in place.

Made from Grade 5 steel, these inch-sized nuts are suitable for most fastening applications.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 and Class 04 steel, these nuts can be used for fastening panels and other light duty fastening applications.

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.

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.

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

With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

These nuts tighten to the left and won’t loosen from counterclockwise motion.

These nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

One-third the weight of steel, aluminum nuts resist corrosion in wet environments.

Bronze nuts are stronger and more resistant to salt water than brass nuts.

These nuts are often used in conjunction with an extra-wide hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.

Stainless steel nuts have excellent corrosion resistance in most environments.

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

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments.
