Also known as jam nuts, these are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels. Some of these screws meet ISO and DIN dimensional standards.

Made of 316 stainless steel for excellent corrosion resistance—including in salt water—these nuts tighten to the left and won’t loosen from counterclockwise motion. For use in low-clearance areas, they’re half the height of standard hex nuts. They can also be jammed against another nut to hold it in place. When used with a standard hex nut, they’re good for fastening most equipment.

These nuts tighten to the left and won’t loosen from counterclockwise motion. Made from brass, they resist corrosion, conduct electricity, and are nonmagnetic. They’re half the height of standard hex nuts, so they’re good for use in low-clearance areas. Jam them against another nut to hold them in place. When used with a standard hex nut, they’re suitable for fastening most equipment.

Also known as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts and distribute the load over a large area. Grade 2H nuts are comparable in strength to Grade 9 bolts. They're about 20% stronger than high-strength steel nuts and are used in heavy machinery, such as earth-moving equipment.

Hot-dipped galvanized steel nuts have a thick coating for better corrosion resistance than zinc-plated steel nuts. They must be used with other hot-dipped galvanized fasteners.

A nylon insert grips the bolt to resist loosening without damaging threads. These nuts are reusable, but their holding power lessens with each use. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.

Steel locknuts without a finish are ready to be painted or finished.

Black-oxide steel locknuts have a dark surface color and are mildly corrosion resistant in dry environments.

Zinc yellow-chromate plated steel locknuts resist corrosion in wet environments.

These locknuts are about 10% wider and taller than standard steel-insert locknuts. They distribute the load over a large area. When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration. They're often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.
