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

About two-thirds the height of standard flex-top locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. Threads at the top of the nut expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. These locknuts have equivalent strength to Grade 8 steel locknuts.

Plain steel locknuts are uncoated and ready for painting.

Cadmium-plated locknuts are corrosion resistant in wet environments. The plating adds lubricity so they thread on smoothly.

About two-thirds the height of standard steel-insert locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. 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, these nuts are suitable for fastening most machinery and equipment.
