Over 48,000 metals now include traceable material certificates.

Choose these locknuts for their adherence to strict military standards for material and construction. They’re low-strength steel, so they should be used for fastening panels and other light duty fastening applications.

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

Threads at the top of these locknuts expand to grip the bolt on all sides for a stronger hold than distorted-thread locknuts.

Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet 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.

Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped.

These kits include one size of low-profile rivet nuts.
