Note 2: The acceptable bolt size ranges for various LocTite
®
threadlocking products is the LocTite
manufacturer’s general recommendation. Specific applications sometime require that a LocTite product is
applied to a bolt size outside the ranges shown here. For example, Milnor specifies LocTite 242 for use on
certain 1" bolt applications and has confirmed this usage with the LocTite manufacturer. You may see
variances such as this in the documentation for specific machine assemblies.
