Review on 🔧 LOCTITE 243 Threadlocker for Automotive: Medium-Strength, Oil Tolerant, High-Temperature, Anaerobic, Blue, 6mL Tube (Part Number: 1330799 - 1330799) by Jonathan Abreu

This is the best Loctite for locking screw or bolt threads, whatever metal you later want to remove. Unlike Loctite 242, you don't have to worry about cleaning all the lube off the threads or even getting oil on your hands. 243 is harder to find, most retail stores have 242. I wish Loctite would make these bottles all blue instead of blue lettering on the red bottle to avoid confusion with #271 or #262 which are permanent threadlockers. Now, if you make the mistake of using the number 271, it's almost impossible to remove it without a blowtorch! Sometimes #271 is sold with a BLUE stripe on the red bottle. The only clue is that no matter what the color of the bottle is, number 271 is always colored red and number 242 or 243 is always colored blue.
