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. They're suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut. A zinc plating provides corrosion resistance in wet environments.

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.
