The Ultimate Threadlocker Competition--Which is the Best?

  • Published on: 25 September 2017
  • Which threadlocker is the best? Which name brand is best? In this video, I use 3 tests to determine which epoxy is the best.
    Products tested: Pro Seal 24206, Permatex 242000, Loctite 242, JB B Weld 24206.

    Great vids ! Thank youMyself i like the loctite blue in a “lipstick” tube #248 very easy to apply just a light swipe on 1 side of a bolt and survives years of harley vibration. Fyi Loctite has these tubes for blue red never seize, pipe thread sealant, gasket tack, copper antiseize i keep them all together on side of my box. On the harleys we loctite or safety wire everything almost as bad as mil-spec helicopter vibration. Try em ya might like em too. I have a pic of the rack i made to keep em standing like soldiers if you like to see it. Thanks again

    If you do a part 2 can you try results after freezing and applying some heat? Not extreme but maybe like an item that sits outside all year ( -20 to 130 F or something). Most items I use thread locker on go through temp changes even if they just sit in the barn or are on a vehicle. I've always wonder what the temp changes do to thread locker.

    From my own personal experience, all you need is a hammer to make a locknut. Take the nut, place it on a hard surface (anvil) and give it a medium/heavy blow with a hammer. This will deform (oval) the nut just enough to make it grip the threads on the bolt. It never lets go.

    I see a video on chain lubes, do you have one on other lubes or cable lube, we use even WD-40, But, also use greases, HD, Disc Brake, blue water soluble, white lithium spray and tub and cans, 3 in 1, oil and A lot more for, cables, door jambs, locks, hoods, trunks, tailgates, door strikers, bicycles, skates, etc, motorcycles, in home and out anything that slides or rubs or moves. I know there are different ones for some of these, but like for brake, clutch, push, pull cables, we tend to use whatever and use that whatever on many things. Oh cable ease, door ease, lock ease. Graphite. Man there might be a few videos there.

    6 1/2 pounds not 5 1/2. There is a huge difference in uses and types of thread lockers, red/blue, Medium/High Strength and more types and more uses.

    Loved the video! However I stopped using the liquids when I introduced to solid/stick counterparts. (No mess) (wax like) Thought you might appreciate the information. Loctite 248 - Medium/ BlueLoctite 268 - High/RedLoctite 668 - High Temp/ Green (400 Degrees)

    Also with Permatex there is thread locker for different temps when I worked at a dealership we had low temp rating for steady bearings and Yokes another temp rating for at the pinions and other places where temp wasn't high and we used high temp for exhaust manifold studs and someone had thread locker there for extreme high temp which never got used

    Why not just use a dial type or parallel bar torque wrench? This was probably the most inefficient test youve ever done.

    Good video. My suggestion would be to also include something that is commonly used but isn't even one of the mainstream products, like for example, I often use some ladies nail polish (lacquer) as threadlocker.

    I know this video post is almost 2 years old but I would like to see how well giving the nut a couple wraps of monofilament fishing line works compared to these.

    I know this is an older video, but I just wanted to know. I had to perform a very similar test recently at work due to product failure. It appeared you used Zinc Dichromate plated bolts. Is that the case?

    Great test, great video. Informative as well; I didn't think there would be as great of a difference as your video showed.

    Id kinda like to see if you could get silicon all kinds of silicon used only to keep a cylinder head on as far as bolting the head on letting it cure and taking bolts out and see which one will last the longest

    Does fastener diameter have an effect on the holding power of threadlocker? Blue seems basically permanent on set screws.

    Wish I would’ve watched this a few days ago before I bolted my PTO onto my transmission with Loctite... time will tell. Thanks for the info, sir.

    have you done the red threadlockers?also, was thinking of this from your epoxy tests, is it possible that as you work up the pressures or loads in increments that the product may gradually weaken before failure? I know youre independent here so thousands of bits of hardware nay not be feasible, not to mention the ludicrous amont of data results to process. keep up the excellent work!

    max holding force is not what makes a tread locker good or bad. thats why there are different strengths of thread locker. what matters is how they hold up over time, in various environmental conditions, and under various loads. you only just barely got into the load testing with the vibration but you dont need a thread locker to hold up under vibration for only a hour or two (normally). also your force measuring technique is pretty poor. at least get a dial indicating torque wrench.

    Every day I come across a new video of yours in my feed, and no matter how ancient it is I always watch them. You make some of the best content I’ve ever seen on YouTube and I hope you never stop doing what you do!

    Before the testing, my guess is loctite. I grew up building and racing dirt circle track cars, and we always used red or blue loctite. Now let's see who's actually the best!!To be fair, permatex and jb weld are also great brands. We always used permatex silicone and jb weld 2 part epoxy. Always performed great.

    Suggestion: use lamp oil (the red stuff) in a diesel engine and compare it to diesel in carbon build up. I've heard they burn the same

    As others have said this test is better suited for high strength thread lock (Red loctite) I'd like to see that test compared with the before mentioned linseed oil, or other glues that will probably be a lot cheaper.

    I like locktite blue, if I needed a stronger hold would just use locktite red. They have like 100 different holding strengths and formulations for various applications. The blue is meant for easy removal and to seal threads to air/liquid leaks. Locktite blue is commonly used in airguns and has always worked flawless. After watching this I do like the JB weld blue. Like locktite doesn’t leave much residue, if anything it looked like less residue. I’ve tried permatex and hated it due to its residue, and also found it had a very long dry time to become air tight (like days... totally unacceptable).

    Loctite 242 is not meant for plated fasteners, like the ones you used. Something about ions and such. I did testing on it at my job and we eventually switched over to Loctite 243.

    I guess the moral of this story is they all work! I don’t think it matters which one took more force to remove since that’s not the goal of medium thread locker.

    Loctite sells tons of threadlocker versions, purple, red, and blue... you only tested the weak version.

    At the end of the day, these thread lockers are medium none permanent. Over the years racing high revving 2 stroke motorcycles, (TZ Yamahas) I always used the loctite product and never had a fastner vibrate loose.

    Your using the wrong loctite, your using the blue with is removable, use the red it’s a permanent bond
