Loctite 242 and 222, what’s the difference?

Loctite 222 and 242

In regards to strength, I stick to this rule of thumb:

For something you tighten with a ratchet wrench that is 1/4″ or smaller, you can use Loctite 222.

If the wrench is 1/4″ or 3/4″, Loctite 242 is suitable.

To add to the confusion; If your ratchet wrench is 1/4″, either 222 or 242 will work.

Enjoy getting things intentionally stuck! 🙂
