How To Properly Apply Threadlocker

We have noticed the bolts failing on some of the machines we have built (such as the CNC and Plastic Injection Machine), and after further investigation we found the issue to be in the way we applied the Loctite Threadlocker.
We made a quick video to demonstrate how to properly apply the thread locking fluid (thread locker) to threads in order to save you the trouble of failing screws in your builds.

Ha, joke's on you. My holes always end up oversized as I'm a shit machinist so no airtight blind holes for me.

[@ActionBOX]

HAHAHAH 😂 . This comment was so funny, you made my day. Hope you enjoyed the video regardless and thanks for watching 😊. Cheers, Dave

[@teeambird2079]

Lol

[@emkoravo]

[@DennisGentry]

I wouldn't do this into a blind hole on an engine casting unless I knew it was a loose fit. It's surprisingly easy to crack the casting when you torque the bolt into the blind hole with uncompressible liquid below it. (This is one reason to always blow out holes with compressed air before assembly.). On the other hand, I can't think of engine casting holes that call for threadlocker, usually just a specified torque, so it probably won't matter.

This minute was one of the most useful minutes I've ever spent on KZbin. Good job!

[@ActionBOX]

Hahah thanks Yuri. Feel free to help us out and share our video with others. We are trying to boost our channel by getting more views. Looking forward to your comments in our future videos 😃

[@drewgossage8842]

The loctite rep always said to do the same. But this is a fantastic visual representation of why, that i haven't seen before. Thanks for sharing👍👍

[@ActionBOX]

Thanks for the comment! Glad you found this helpful. Feel free to help me out and share with a friend :)

[@Ktron99]

Fair enough unless the threads a tight tolerance, you'd end up hydraulicing the hole, common on engine bolts when there's oil in a hole it cracks the casing

[@thewespaul6520]

Can’t believe this isn’t mentioned more here, this is why you don’t do this method.

[@bronzemoongames]

He is actually right about the principle but the execution is not 100% correct. Loctite advices to apply the threadlocker to the 3rd or 4th thread from the bottom on the threads of the body. So, that there won't be any remaining adhesive, which stays uncured.

[@ytubeanon]

I suppose the solution is to apply threadlocker to the bolt, screw it in and see if it bubbles out - no: leave it, yes: remove bolt, drops into hole then screw it

[@elebeu]

That was my first thought also.

[@clivevreeswijk4555]

Absolutely, I had it happen with too much loctite on a motorcycle case, thankfully it just popped out the end and didn't ruin the whole thing, used a copper washer to prevent oil leak.

[@shawn576]

Quick and to the point. Thanks!

[@JB-pb9xv]

This actually answers my question better then allot of the videos testing these. Because the difference actually depends on whether you have an open or closed / blind hole that you're screwing into. As to how the thread locker will apply.. My other question which I think would help in these closed ended holes as well. Is whether you should allow the Loctite to cure for awhile, before driving the screw in..

[@ActionBOX]

Awesome, I’m glad we could help. Many Loctite thread lockers are anaerobic adhesives which means they harden or “cure” in the absence of oxygen. Hence no need to wait. Hope that helps. Cheers, Dave

[@chadkulikowsky5162]

We at my place of busniness have devoloped a better version on threadlock. We call it CROSSTHREAD.

[@mortarriding3913]

Thank you algorithm. I was just about to do some threadlocking.

[@That.Guy.]

I was actually looking at it on Amazon which makes me wonder how are KZbin knows about it

[@johntechwriter]

Very informative, and just the right length. Top marks.

Everybody is gangsta until your bolt goes upside down.

[@chemicalcorrosion]

Several years ago I used thread locker on an Anet acrylic 3D printer build. The entire thing CRUMBLED due to the thread locker affecting the acrylic.

[@ActionBOX]

Fair Point. We simply used acrylic for its clear properties in order to make this phenomenom visually evident. Hope you enjoyed the video regardless 😃

[@chemicalcorrosion]

@actionbox 👍very good demonstration.

[@UnvarnishedTarnished]

@@ActionBOX When should you use thread locker / when shouldn't you? I've never used it before

[@ActionBOX]

@@UnvarnishedTarnished use thread locker anytime your bolts go on something that vibrates or is exposed to vibrations. Hope that helps 😃. Don’t forget to share

[@UnvarnishedTarnished]

Hey man, can you make some more Projects with masso? Im really liking the Idea of the Board but here in Europe the price after taxes is almost 800€...

[@ActionBOX]

Absolutely, I will but not in the next little while as we are working on another really unique machine that does not rely on Masso, but pure code instead. Thanks for supporting the channel 😃, Dave

[@ToeCutter454]

betting this stuff is probably different from the pre-coated bolts you get with some fasteners that have a ring of blue loc-tite on them otherwise you could just go the route of putting it on the bolt as such, letting it cure for a day or two then using it when you need to and the friction creates the bond when you run the bolt into a threaded fixture.

[@GamingLiveHDChannelPH]

So can someone have an tutorials on Laptops especially the LCD Hinge part?

[@mikegLXIVMM]

Another tip: keep thread locker away from acrylics. Even a small amount will destroy the acrylics.

[@shroey20]

I dont understand. What's a blind hole?

[@Keri-hl7qk]

When the hole don't go through the material

[@andyspoo2]

That's OK if your threaded hole doesn't go all the way through, which many do. What's the best method if the hole does?

[@ActionBOX]

Put a line down on the internal threads would be my guest. Although there are other great options for open ended holes. Cheers

[@ghostid544]

Locktite made a similar video a few years ago showing this for blind holes.

[@theharvestfloor1]

I tried this, but all the threadlocker fell out the hole straight away.

[@Majlis-Alalaiwat]

What if it is throgh haul?

How to apply if iam gona attach two objects

[@durimmiziraj4815]

Apply it to the bolt, and let it dry. The technique is good enough for car manufacturers.

[@ActionBOX]

Good to know. Thx

[@bernardmclake3898]

Different product used for pre-applied thread locker. It consists of micro spheres with the anaerobic thread locker inside. When the threads engage, the micro spheres tear open and the thread locker can do its job.

[@tompetry8589]

What if you’re bolt is horizontal?

What if the thread is upside down so the liquid will fall out

[@Megiddo426]

But what about a REGular non-blind hole??

[@byron3373]

I may be wrong but I think that method could cause a hydraulic lock, not good then .

[@ameliabuns4058]

I felt very betrayed when I found out this stuff harms plastics :c wish they had a plastic friendly solution that wasn't based on superglue! I have metal nuts in my parts but they have to pass trough plastic

[@ActionBOX]

I would agree that its never fun to find that out the hard way 😢. I do believe there are plastic safe alternatives but I assume they are much more expensive. I guess we have to work with whatever is within our budget as hobbyist 😜. Thanks for supporting the channel 😃, Dave

[@Trent-tr2nx]

Loctite 425 or Plastic Assure Threadlocker is safe for plastic-- It's cyanoacrylate based. Maybe it's just a fancy super glue. Also take a look at Vibra-Tite VC-3 which is a removable threadlocker not made by Loctite that should work with plastics.

[@ameliabuns4058]

@@Trent-tr2nx i don't think vc-3 is made by loctite, But I always wanted to get some, hard to in my country, and priceeeeey

[@hamidizadi]

What if the hole is upside down?

[@ActionBOX]

Then you have bigger problems 😜

[@GUCR44]

Could get hydro lock if you use to much.

[@ActionBOX]

What’s that? Please enlighten me. Thanks 😊

[@GUCR44]

You can fill a blind hole with fluid (oil/thread lock) so when you screw in the fastiner it can blow out the bottom of the housing from extreme hydraulic pressure.. Old chevy water pump housing and blue rtv in the hole is how I learned this.. Peace man

[@mikecunningham3423]

This only works in blind holes

[@ActionBOX]

As stated in the video, Correct.

[@OEMPlus]

woah. dude. okay, im a dummy. shit.

[@ActionBOX]

Haha glad the video helped! Never too late to learn new things 😉 thanks for watching and supporting our channel! - Dave

[@badgt1974]

I think that's way to much Threadlock, I do it the same way but all you need is to put a little bit on one side and it will still cover the bolt as you thread it in.

[@ben.aka.bigben]

Yea not every screw hole is facing down with gravity helping it my guy

[@jimmyurbanski4970]

Understandable....yet. Good luck on trying to remove the bolts when needed. The thread locker is only supposed to be applied sparingly per application "a drop across a few threads" Then allow to fully dry and cure before fastening in the hole.

[@ryanokeefe12]

I think you've misread the tech data/user guide for this stuff. It mentions letting the threads dry after you clean them... not letting the thread locker dry. Thread locker is anaerobic, meaning it dries in the absence of oxygen. It will never cure before installing it. It also acts as a sealant and lubricates the threads before it dries so that you don't get binding. Unless you're using a specialist formulation, it's not possible to allow it to dry before installing the thread. Even if it could dry, it's not the correct method.

[@tallisman57]

This is one of those duh moments when viewing the world as a whole... If people continue doing things that are inferior and not come to a conclusion on the own especially when it's this simple of a task, it doesn't say much for our future now does it. It has become known recently that the planet the whole, people are becoming dumber and dumber.... Well let me back up a hair, the dumb are becoming dumber, while the intelligent are becoming smarter... Although this video might be necessary, it never should have become necessary in the first place.

[@ActionBOX]

Hmmm. I’m not sure I would consider this totally intuitive, otherwise I wouldn’t have made the video 🤔. I think some people just have less experience, and this video is there to help them out 🤷🏻‍♂️. Hope you enjoyed the video regardless

[@ascgyu]

Never fill the hole with thread locker !! How will you remove it ? Its not glue.... its thread locker. If you do that on a gun, you are in a bad shape.

[@ActionBOX]

I’m not sure what you mean, this product is used all the time in practically every manufacturing industry. Is there a specific reason not to use it in a gun? You can always get different grades of strength. I’m a little confused 🤔

[@vglnte1]

Hydro locked .....

[@Notorious_Crypto_Bird-Dog]

Useless when your bolt is going up and not down...
