Square MF Locknuts
Square MF locknuts provide tight connections between bolts and nuts to prevent loosening over time. The MF locknut can be used as a locking nut on the back of square.
These concave square MF locknuts are designed to spin freely by hand. When tightened down over an existing nut, the arch is flattened causing a permanent set. Hot dipped galvanized MF locknuts are tapped oversize to compensate for the corrosion resistant coating on the bolts.
