Metric Medium-Strength Steel Top-Lock
Distorted-Thread Locknuts—Class 8
Zinc-Plated
Yellow Zinc-Plated
An irregularly shaped thread at the top of the nut 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. Comparable in strength to Class 8.8 bolts, they're suitable for fastening most machinery and equipment. A zinc or yellow-zinc plating provides corrosion resistance in wet environments.
