Hexagonal Nut Nylon Insert Zinc Plated 1-1/4-7 Grade 5

A nylon insert grips the bolt to resist loosening without damaging threads. These locknuts are reusable, but their holding power lessens with each use. They are suitable for fastening most machinery and equipment. A Zinc-plated steel provides corrosion resistance in wet environments. The nuts have a 1-1/4-7 thread.
