About Nuts, Materials, and Finishes

High-Strength Steel Top-Lock
Distorted-Thread Locknuts

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

Extreme-Strength Steel Top-Lock
Distorted-Thread Locknuts

These Grade 9 locknuts are about 20% stronger than high-strength steel locknuts and are often used in heavy machinery, such as earth-moving equipment.

Steel Flex-Top Locknuts for Heavy Vibration

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

Metric Steel Flex-Top Locknuts for Heavy Vibration

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

Steel Thin Flex-Top Locknuts for Heavy Vibration

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

Steel Extra-Wide Flex-Top Locknuts for Heavy Vibration

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

Extra-Wide Thin Flex-Top Locknuts for Heavy Vibration

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.
