Metric Conical Hexagonal Nut Zinc M8 * 1.25 Grade 10.9

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 Yellow Zinc-plated steel provides corrosion resistance in wet environments. The nuts have a thread of M8 * 1.25.
