Excellent overview of Loctite Red & Blue!
And thank you so much for doing the superglue comparison. We ended up using superglue based on your results as we don’t need resistance to high temperatures. 👌

excellent video, thanks for being so exacting with your method, and so impartial. I look forward to more

A DIY version of an industrial vibration test 😁 Nice 👍🏼. I have the same experience from professional tests. Red Loctite is good for moderate vibration. If you had continued the red would likely have lost the clamp load as well even if the nut had stayed on the bolt. If you are not already familiar with it, google Junker test. It’s considered the gold standard for fasteners. Thanks for another good video.

Your test are really good I like how you did everything very controlled and I learned a lot

[brandonbarker]

As a industrial mechanic this is most interesting. Thank you sir.

[SevenDeMagnus]

Cool, red is the tougher one. I have both w/ screw spring washer combo sometimes.

God bless.

[mhn...]

Well done and thank you for sharing your experiments with us. Thumbs up also for your patience of conducting those tests.

I have always wondered about this and now know, thanks. Always thought red was one and done almost like welding it on but not so😊

[Fred-mvfx]

Nice. I have considered using blue oil-resistant loctite on motorcycle suspension fasteners but I think I will continue to stick with red.

[rooster]

Test old school mechanical methods; staking the outward nt to bolt margin and then using safety wire through a drilled hole through thenut and bolt. I think I will start spot welding lol

[rafaellastracom]

Excellent, excellent test. Great information.

Thank you for this video! Likely saved me a ton of time and anguish on my next project.

So many mechanics don't realize how important it is to have very clean threads for Loctite to work its best.

[treebarbers]

Based on what I can conclude from your findings, in high vibration applications, I am going to use red locktight 271 on bolt threads, in combination with spring washers AND nyloc nuts. Possibly a second nyloc nut if in doubt. Thanks

I would recommend trying higher purity isopropyl alcohol. The stuff meant for antiseptic purposes may contain oils meant to avoid drying the skin so much. Try something meant for electronics repairs because those are designed to evaporate to fully clean surface.

The hardware looks like it may be plated in some way. Please note that Loctite needs active metal ions to fully cure. If you have corrosion resistant hardware, you have to use Loctite primer to get full cure. Super Glue or CA adhesive does not need active metal ions.

[AlWall-ud]

So for your torque test I wonder if using brake clean to clean parts and then using the locative brand primer would be better or not.

[larryphillips]

Now let’s test those tiny tack welds as a comparison

[theodorehile]

Loctite will tell you that on plated fasteners, use of one of Primer N or Primer T will give best results, as they drive the compund to full cure. The factory derived breakaway and prevailing torque numbers are determined off black iron finished steel nuts and bolts. Using heat on the assebled parts will achieve better results too, but that is not practical.

[BushPigADV]

For torque purposes loctite is considered a lubricant. A wet torque spec should be used should be used on all the hardware including the control. That said, i think the difference between wet and dry is like 20% so only a 2.2lb value in this case. I don't think it would make or break your experiment.
