The Honest TRUTH - How Much Stronger is Loctite Red than Loctite Blue?

Find out how much stronger Loctite red threadlocker is than Loctite blue threadlocker on fastened nuts. I tested and compared the strength of Loctite's permanent 271 red threadlocker and removable 242 blue threadlocker. Learn what I found out.

Thanks for not dragging this out for a half hour.... I like getting right to the point.

Everyone likes to think the red loctite is "permanent-forever-welded-torches to get it off" but in reality it only requires a bit more torque to break it free. Rust will always cause more problems and realistically loctite prevents rust so it probably makes most bolts easier to remove over time in the North.

What a much more pleasant test than those conducted by Project Farm. No shouting. No unnecessary repeating. No resulting headache. Good job.

While interesting-You MISS the point of Loctite-it is to prevent vibration movement-like a nyloc nut-not to resist tool useage.

I always felt like the red was used for breaking strength and the blue helps with backout strength so a screw wouldn't walk out from vibration. That's how I use the red and blue in the rc hobby. Red if I don't want it to move at all and blue if I just need to make sure the screw doesn't fall out if it does break loose.

BUY RED 😂. Thank me

[@davidbrewer7937]

I would like to see a similar test under vibration conditions. Hang a known weight from each sample & subject the bar to the same vibration then compare time to break free for each. Loctite is primarily designed to protect against vibration & temperature related expansion & contraction effects, not so much for static rotational loading.

[@georgecurtis6463]

In most uses it's just to prevent backing off of nuts or bolts, etc. The blue is for the ability to hold but still be able to back it off without damage. The red is to hold in more adverse conditions and be much harder to loosen and back off. I have had situations were red has been used and did not back off this easily. And yes, at times it did require me to heat it up. To say that this is not required is foolishness. I never use red unless I plan on basically never needing the nut or bolt to ever be loosened. Otherwise it's always blue. And all that is with or without lockwashers and such. Just another safety step. Specially on fasteners that could cause serious damage or injury.

Blue is used for more than holding strength. Silly comparison.

Inactive metals require activator. This includes "any plated parts, anodized aluminium (i.e. Alodine® or Iridite ), titanium, stainless steel, galvanized steel, zinc, pure aluminium, cadmium, magnesium, natural or chemical black oxide, magnetite steel, Iconel or any of your precious metals such as silver or gold."

[@lessanderfer7195]

The point of Loctite is to keep the nut from backing off, not to keep it from being able to be undone. If you don't want the nut to ever move, weld it.

Thank you for the comparison in a short video. It was bullet point, accurate and didn't make me fall asleep. Props!
