Threadlocker Application
Refer to the manufacturer’s instructions found on the container before use, in addition to the following
information:
The procedure for correctly applying Loctite 242 and Loctite 243 (Blue color) threadlocking is as follows:
•
Clean both of the joint faces with Loctite 7063 cleaner or a lint-free cloth moistened with acetone or
another suitable solvent.
•
Apply Loctite 243 sparingly but sufficiently enough to fill all engaged threads. (This product performs
best in thin bond gaps [0.05 mm]).
•
Install the threaded components and, where known, torque to the applicable torque value. If the torque
value is not known, tighten so that it is firmly secured.
•
Clean off any unwanted adhesive.
•
Allow the Loctite 243 to cure before subjecting to load.
•
Where the cure time is unacceptably long, or large gaps are present, applying Loctite Activator ‘N’ or
‘T’ to the surface will reduce the cure time.
For general Loctite specifications and application details, refer to Loctite manufacture’s instructions.
NOTE: Because Loctite 243 is oil-tolerant, it is not necessary to meet the same standard of oil-
free cleanliness as for Loctite 242.
NOTE: The cure time will depend on the materials used, the ambient temperature and the bond
line gap.
