These nuts are suitable for fastening most machinery and equipment.

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

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

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

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

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.

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

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.

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.

All of these stainless steel panel nuts have some chemical resistance.

These panel nuts are knurled to provide a secure grip for tightening and loosening by hand.

Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

These metric locknuts have good chemical resistance.

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

About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.

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

These locknuts, also known as Fuji locknuts, maintain their holding power with reuse longer than nylon-insert locknuts. They have a spring ring that creates tension as you tighten the nut, keeping them in place.

Also known as collar nuts, these metric nuts have a flange that distributes pressure across the surface, so you don't need a washer. Made of high-strength Class 10 steel, they’re about 25% stronger than medium-strength steel flange nuts.

Made to Japanese Industrial Standards, these nuts fasten most Japanese machinery and equipment without a washer.
