As a machinist/mechanic I know the threads do not go all the way to the head of the bolt. It looks like you were bottoming out the threads on the nut. If you were to put a washer on before the nut it would insure the nut wouldn't bottom out. I've seen thin sheet metal do this. Nut is tight but sheet metal isn't.

Thank you for your work, great to get a better understanding for these product and the different application methods

You have to clean any oil or grease off the threads for the very best bond. Loctite 680 retaing adesive is on another level, if done right it's insanely strong almost like a weld.

Nice! This exactly the video I was looking for. Thanks :)

The researcher we actually need . Been wondering the real life differences

Excellent demo. As a Harley Davidson enthusiast I need to use locktite.

very interesting to see how well the 243 performed overall. great test. Keep it coming!

What do you use to clean this stuff up if you are reinstalling the bolts, cause the bolt hole is going to be gunked up with dried up loctite? if you don't clean the threads properly wouldn't it affect your torque specs during reinstallation?

I thought the point of these was not to add a ton more torque but to stop the parts loosening under vibration.

Great video. Thanks!

The Green Loctite is some crazy stuff, last time I used it a bearing race had been damaged by a bearing not being replaced when should have so the new bearing wouldn't stay in the race. Added some Green Loctite and waited an hour and that bearing will now need to be heated out of the part but it prevented the replacement of a $2800 roller. lol

Loctite thread locker needs to be applied correctly for it to achieve it best performance. Put it on clean oil free nuts and bolts will give you a fair outcome but it takes a long time to cure correctly. If you are serious about it you prime both components of the fastener , flood and assemble as quickly as possible. Loctite 7471 works very well to ensure a full cure regardless of temps. It also makes a nice quick set gasket if using 5188 or 515. Unless you have primed the surfaces with the proper primer the set strength and vibration resistance is going to be a lot less than 100% of capability. All of the compounds appeared to have not fully cured when tested.

Interesting test 👍🏻

We were told by loctite representative to use primer, it sets up quicker and more solid. Also Loctite seals the threads from rust and outside contaminants. We used 270 to keep bearing shell from turning on casing and always had to heat them out. My experience with this product.

Great I thought two drops was enough. Have used Red in error. Had to destroy coupling with Map gas to remove bolts.

The thing I don't like about 290 is people confuse 270 for it. They just see green.

Did you ever hear of Newton meters? Nm

Thankyou

What about testing the Loctite 542 for hydraulic oil pressure.

271 is also a sealer and works to higher temps than 243.

These bolts had a shoulder down at the head, so you weren't torquing against the threads, but rather just the very bottom of the nut against that shoulder.

i caught a trade show in Australia many years ago they had a Loctite both there they said had an expiry date on the bottles got to the point if the bolt and nut had Loctite on them i am not going to use them again

Nice video I'm a retired Electrician used thread locker a bit through my career not as much as you have. I just want to know when the hell did you steal my deep well socket it has to be mine it has 3 hash marks on it! That is how I marked all my tools with a file or 3 dots with a punch when I seen your tool mark I just thought I'll be damn.

Active or inactive metals? With Inactive metals you need the primer.

Nice research, I'm certainly no expert in this field but I'd assume that by not following the manufacturer's instructions and applying more that the recommended amount could cause some lower grade bolts to break upon disassembly if torque requirements are close to the breaking strength of the bolt. I'm careful to apply the instructed amount for that reason.

HOWdy D-Bm ,,, Thanks for the COMPARISON COOP the WiSeNhEiMeR from Richmond, INDIANA ...

"The more you use, the more you get" I love it. Also where is the final data in summary form?

I use RED 271 on BIG mixers that have crazy high torque to retain big bearings in aluminum housings and various large bolts 3/4 +++ it always needs heat to come me apart The press-fit repair silver paste is also a pretty impressive Hail Mary

I don't understand how the 271 is supposed to prevent tampering (per Loctite) when it comes off with such little torque.

Loctite is anaerobic. NO air means it sets. The red stuff not working may mean that there was an air gap at 15 psi

Whenever I use Loctite, it goes on heavy and a long curing time. I'm using it because I don't want something critical to come apart. 3 drops, never.

I like your torque meter. What brand is it ? Can I get it on Amazon?

Is is possible to remove LOCTITE 243 residue from painted surface? I used Loctite 243 for the screws to attach black painted bar ends weights to the handlebars of my motorcycle. Unfortunately, I had some Loctite residue on my hands during assembly, which left some ugly fingerprints on the shiny black paint of the new bar end weights. Is it possible to remove the loctite residue from the bar end weights somehow without damaging the paint? Maybe with chemicals, heat or buffing?

Should have left them to cure for about a week. Pretty much all of them look to be uncured

Can learn what is mistake of loss glue performance

Project farm tested these. The ones you tested are absolute junk compared to Vibra-tite

Loctite Gell is good

So what we learned is . The bigger the job the bigger the gob

How much cure time was here?

Did you degrease and 243 seems better than 242 if any oil might be present I don't even buy 242 any more

What is the massive constant buzzing sound in the audio?

Try loctite 272 hands down the strongest 🤜🔥🤛

Loctite 290 3* more that blue, i think.

You degrease it first then use 1 dot

Nice Transformer Buzz in the background! Lol!

Well first there is at least four types of red LocTite brand and each is for very specific uses same for Green which has 290, 294 & 638 all with different uses. As far as how & how much look at a Holly Davidson manual which will state which red LocTite & how many drops to use for each Specific fastener. So it may request two of more red LocTite types for several bolts in the same area. I was shocked just how vast their types & usage and different brands are all over the place too. Permatex, J-B Weld Perma-lock, LocTite but to mention a few.

loctite rumours and loctite secrets ended on an experimental base.
