Everbilt 5/16 in. -18 Coarse Stainless Steel Nylon Lock Nut

The Coarse Stainless Steel Nylon Lock Nuts from Everbilt are hexagonal nuts that are paired with the same material, finish and grade to create a secure and tight hold. The nylon ring produces rotational resistance and prevents loosening. It also helps add extra corrosion resistance and resist vibration. Check the packaging for the inner diameter and the numbers of threads per inch or thread pitch.
