- What Thread Lock?
243 it’s blue, and it will be fine for everything that you don’t want to vibrate loose.Posted 4 years ago
222 is ok but it’s low strength. 243 isn’t crazy strong like a chemical weld!
The older version was 242 but the 243 is oil tolerant so if you haven’t cleaned every trace of oil off both surfaces it will still go off.
Sorry to sound like a loctite geek but I went on a loctite course through work to raise awareness into suitability of their products in different applications.
