Extreme-Strength Steel Hex Nuts—Grade 9
These nuts are about 20% stronger than high-strength steel nuts and are often used in heavy machinery, such as earth-moving equipment. They're cadmium yellow-chromate plated to resist corrosion in wet environments.

Extreme-Strength Steel Top-Lock
Distorted-Thread Locknuts
These locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts. They thread on from the bottom of the nut, allowing more threads to engage the bolt before tightening for easier installation than center-lock distorted thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable. About 20% stronger than high-strength steel locknuts, they're often used in heavy machinery, such as earth-moving equipment. A cadmium plating provides corrosion resistance in wet environments and adds lubricity so they thread on smoothly.
