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

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.

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

Straight to the point, no nonsense yapping, thanks for sharing.

Thanks for not wasting our time with a 20 minute video.

I was not looking for anything like this video. It just showed up on my front page. However, I’m liking and commenting because you didn’t drag this out and it was informative. Good video and straight to the point.

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.

Was a great reinstatement for the hand-loosening afterwards. Blue was easy to remove but enough to stop rattling off id suppose. Thanks for the video

Finally some one who doesn't drag on and on. Thanks!

subscribed simply because he is to the point and gets the info quickly, thanks

They are made for two different applications blue for retaining a bolt or nut from vibration and made to be removed with regular tooling the red is for locking application and heat is needed to brake the bond to remove if you clean the matting surfaces they work as intended .

Short and to the point, excellent video!!

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.

I love how you covered all the variables. Nice one Dad =)

On tiny fasteners, M3/M4 on my RC cars back in the day, blue was more than enough! In that case, it was more for stopping stuff from spinning loose due to vibration.

New subscriber. Thank you for being brief, scientific and sharing data. Much appreciated!!!

Good test. I've ridden Harleys for the past 35 years, and I put blue Loctite on EVERYTHING to keep everything together with all the vibration my bikes put out. It does the job. I use red on things that I don't have any intention of removing like sissybar sideplates, and accessory mounts.

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

Plain and simple explanation, yet very informative. Thanks.
