Very comprehensive. Job well done. Thanks.

Great video, thank you!

[@HacksbyDad]

You're welcome! Thanks for the feedback!

[@onlythetruth883]

Thanks. Experimentally true. I need to view again to see what's really happening.

[@HacksbyDad]

Thanks! I appreciate the feedback. 😎

I don't think the primary use of green Locite is not nuts & bolts but rather for securing pressure fit for a more permanent bond, say like two machined surfaces with a pressure fit. I've seen it used on assembly of certain fire arm parts but it is similar to red in that it releases more easily with heat.

[@HacksbyDad]

Thanks for watching the video and the comment! 😎 The instructions say green Loctite is for #2 to 1/2" bolts. I got curious after someone mentioned it in the comments of one of my other videos, purchased a tube, and tested it. LOL

[@alfredocuomo1546]

@@HacksbyDad As far as I've seen it was for pressure fit because it was supposed to wick better than red but I guess they all can be used for nuts & bolts just by the nature of the beast. I actually watched a few of your videos, very good and nice presentation. Thanks for the reply.

@@alfredocuomo1546 Thanks for the kind words! Much appreciated! I'm learning with each video and having fun in my old age. LOL

[@Rusty-Metal]

​@@alfredocuomo1546You're confusing this with 638 green which is a retaining compound.

[@MikkoRantalainen]

Great tests! I was really surprised to see how well wicking worked with the red loctite.

[@HacksbyDad]

Yeah... the red wicking results were surprising. That was a fun experiment!

[@jonesgang]

They all have there specific uses that is why there are different types and strengths. Red, Blue, Green, Purple, Yellow that I have used. Could be more. You have to be carful when using threadlocker on smaller hardware, using the wrong one will cause you a bunch of headaches. Use red, green, yellow on a 4-32 screw and if you have to remove it, you will be breaking out the drill and tap.

[@mrow7598]

You use heat to remove those smaller screws.

[@borisj4054]

Just read the selection sheet and work by the instructions. Colour has little to do with it, it’s the type number. 200 series can be undone with normal tools, the 600 needs heat to release.

Rebuilding large air compressor. Parts sent to me by Ingersoll Rand recommended green locktite. 2 years now ,compressor runs daily for many hours at a time. No Problems. If green is recommended, I'm using it.

[@HacksbyDad]

Good to know. Thanks for sharing.

[@jimself9395]

@@HacksbyDad The green recommended by Ingersoll I believe was #638

I think when people talk about green loctite they are talking about STUD LOCK. The stuff that is almost impossible to undo. That is a different product to the one you tested...

[@petermichaelgreen]

Yeah, loctite make a bunch of products, referring to them by color is highly ambiguous.

[@woodrowsmith3400]

To me, Loctite is one of those companies that sell products like the industrial products from 3M. If they say it will work under 'these' conditions and you use it under 'these' conditions, it will work as advertised. Period. I learned about L290 from a retired Air Force jet engine repair man. When I went to work at a NAPA store in the eighties, I attended a chemical seminar sponsored by Permatex. I asked about 'green' Loctite. Dude looked at me kinda sideways and asked "What are you talking about?" I said "290." He grunted and took another question. At the meet n greet after the seminar he walked up to me with a small tube of 290 on a NAPA branded Balkamp card. "Here," he says "I've been here three years and no one has ever asked me about this stuff. What does it do?" I told him as much as I knew about it at the time. I keep at tube in my workshop toolbox around at all times right next to the tube of red. I use far more green, because it fits what I need a thread locker for...better. This video justifies my (personal) claims. Thanks!

[@jameshaulenbeek5931]

A primer is recommended on zinc coated bolts, as it doesn't bond to the zinc as well as plain, clean steel.

[@Bob_Adkins]

Not so great on AL and SS either.

[@Bob_Adkins]

I like green because I can apply it after the threads are already tightened and a fraction of a drop is enough. That way there's less chance of getting it on my fingers, and it really stinks. If you have a porous or cracked weld or forging that leak, just a drop will usually wick in and stop it.

[@HacksbyDad]

👍😎

[@philliphall5198]

I use green for races that are not very tight fit is all

[@georgeblair7129]

what happens if you mix all the colors?

[@s0nnyburnett]

why haven't I thought of this

[@johnbravo7542]

The world will implode😁

[@Bob_Adkins]

@@johnbravo7542 That's just it, it can't implode because it would be too stuck together.

[@giuseppe6631]

can yuo repeat the test pls ? but this time for more reliable results degrease all the pieces to avoid dirt and oil contamination

[@Brian81-207]

Just mix them both together

[@thorb5191]

Green is for bushings and it wasn't even applied the same. Your "test" means nothing.

[@HacksbyDad]

Thanks! I think you’re referring to retaining compounds for bearings and bushings like Loctite 260. Loctite 290 is a wicking threadlocker. 😎
