NOTE: The acceptable bolt size ranges for various LocTite ® threadlocking products is
the LocTite manufacturer’s general recommendation. Specific applications sometime re-
quire 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.
