Medium-Strength Steel Nylon-Insert Flange Locknut, Grade F, Zinc-Plated, 3/8"-16 Thread Size
These locknuts have a nylon insert that firmly grips threads to resist loosening and a flange that distributes the load over a large area.
They’re reusable, but their holding power lessens with each use.
Made from Grade F steel, they're comparable in strength to Grade 5 bolts and are suitable for fastening most machinery and equipment.
A zinc plating provides corrosion resistance in wet environments.
Height includes the flange.
