• Allied Bolt Suggest Best Practices/installations notes:


    • Used as a locking nut on the back of nuts.
    • Hot dip galvanized to meet ASTM Specification A153
    • When concave side of locknut bears down on top of square nut,  the arch is flattened, deflecting the nut threads from their true helix  and causing them to firmly grip the bolt threads.
