    Former Loctite sales rep here. Zinc is a fairly active metal, which is why it's used for sacrificial anodes on boats. You won't gain much using primer/activator. That product is meant for passive metals, such as stainless steel. What the primer does is add another cleaning, and introduces copper ions, which will cause the Loctite to set up. Try your experiment using 316 stainless bolts and nuts, passivated if you can find them.

      ​@Johnny Table Use a Liberal amount of the right kind of antiseize, and you'll be fine. This excludes the possibility of using threadlocker of course, but nylock is better anyway, except when you can't get to it with a powertool of course.
      I've built helidecs from extruded aluminium girders that snapped together like laminated flooring. These were then secured with stainless bolts and clamps. We did this as a team, and I was new at the job. I held everyone back because I used too little antiseize on one bolt, and I had to cut it, because it had welded itself together. It's remarkable how little patience a foreman can have with young boys, fun times 🫤

    Try the test with the fasteners torqued when assembled, probably with holes through a steel bar. This would approximate real world use as the nuts loose on the bolt aren't as "anaerobic" as when stressed under torque. I would definitely be interested in seeing those results. Thank you for your presentation.

    • @andrewbermel1099

      @Kalvinjj ปีที่แล้ว +30

      Same as I was wondering, as far as I knew, thread lock only properly works when you torque the bolt/nuts. I even used this to my advantage when assembling some structures, just put the thread lock in the bolt, and hand tighten it so I don't lose it around. No need to rush, it will only really get properly locked when tight.
      It really was annoying when I did have to remove some bolts because of whatever stupid mess I did, but that's the thread lock working as intended, can't complain there.

    Been a mechanic for 40 years & red lock tite is used for bolts & nuts that are imperative that don’t come loose like driveline bolts or any bolts subjected to torsional vibrations- bolts that go round and round. Blue lock tite is used for smaller bolts and bolts that clamp components to something like p/s box to frame. A shot of brake clean before installation if the bolts are greasy. Once the bolts are installed they usually don’t come back out for years so time isn’t an issue.

      I use the same logic on rifles: muzzle treatments (especially JP Recoil Eliminators) get Loctite Red, everything else gets Blue.
      Context: muzzle treatments tend to be directionally biased, so if you set them up in the wrong orientation they can be worse than not installing them at all.

    I believe that what many people don't realize is that both sealants are anerobic sealants meaning that they cure fully in the absence of oxygen. When the bolt/nut is tightened all the air is squeezed out causing the sealant to cure.

      True. Liquid LocTite will stay liquid if left sitting out in the open. One thing I see most people and 'testers' do incorrectly is use way too much on the fasteners. A drop or two is all that's needed...not soaking the fastener until it drips. That doesn't help, and just makes a mess. Also, the reason there are different part numbers is the size of the fastener. They have specific uses.

    I just came from a reddit post that was basically a guy ranting about how everyone uses loctite wrong and that it's basically useless on inactive substrates unless you buy the kind of loctite specified for it or use the primer. It got me worried because I've never used the primer and have assembled a lot of stuff with loctite that is plated or anodized. This video proves that it's nearly as good without the primer. Unless it's an absolutely critical part, I'm going to continue to forgo the primer.

    I have had things where red Loctite was used and shouldn't have been. It seems like the finer the threads are, the stronger it is. I've had a couple of gun barrels that had red applied to them and they had to be heated up to even think about getting the nut off without damaging it. A friend had a homebrewed radio with the front panel held on with about 20 hex screws, and the builder used red Loctite on every one of them, apparently not thinking the panel would ever have to be removed for future repairs. Even when we heated the screws with a soldering iron, some of them got the hex stripped out and others bent the allen wrenches we were using. When we put it back together, we used new screws and Vibratite.

    Manfactures often include an unnecessary step to either sell another product (ex. primer) or give their lawyers a loop hole if their product fails (clean dust free surface) when they know that most of their customers cant abide by it. I use Loctite on light fixtures that were installed on a bridge when clinton was in office, at 3 am, in the rain, cold salty air while on a boom lift with a head lamp. In these conditions i can barely keep my sandwhich clean let alone a bolt. Use lots of loctite and torque to specification. If you need to loosen use either a brake bar or a torch to burn it off.

    I've never bothered with activator/primer and just normally used red or blue depending on how serious I am about wanting something to not come apart. Bond strength is also going to be much more significant depending on surface area of the threads, so keep that in mind with larger, coarse thread nuts and bolts. I've never had red fail to keep something secured.

    We use a red sealant on our pipes at work. We generally only use the primer when we are dealing with Stainless as it doesn't stick very well to the stainless and just runs off. The primer helps it stick to the metal better. In brass or copper it doesn't seem to matter as much. We don't use a lot of zinc.

    Seems like there wasn't enough of a difference to worry about. I think I will continue to use it as I always have! But it's a little odd to me that the non-activated breakaway torque raised with 72 hours, but then dropped again. I think there may be some variability in the quality of the bolts and nuts. A better test would be to test 5 of each without timing, then average them, removing the highest and lowest!

    The use of loctite is to prevent a bolt or nut from backing out further from their initial tightening torques if that starts to come loose for some reason. If it's for later work, the red is for stuff that one Hope's will never be loosened again or in a very loooong time. Blue is to hold in blessed stressed or torqued items while still being able to disassemble without going through any special efforts. Torque release tests mean little to me because at no time are the hardware being turned by an outside force. So clean with brake clean and use the loctite of your choice and move on. If one is really concerned, then just safety wire the hardware.

    I found this test interesting, informative, and thought-provoking. I wonder if you would have gotten different results if you loosened torqued samples. I'm thinking (and I am hardly an expert on the subject) that you tested the shear strength of the cured threadlocker and not the ability of the threadlocker to effect sliding between two clamped surfaces. Would the results be similar if the same test was performed using Loctite 243 or 222? That's the real plus of videos like this - makes the curious think about things that they long took for granted. Thanks for your effort and sharing of the results!

    • @shannonhill3356
      @shannonhill3356 ปีที่แล้ว

      Well loctite also cures in anaerobic environment. When the nut is torqued tight, it seals out the air, and allows the loctite to properly cure. This is usually when breaker bar is necessary. He basically just had some half cured, maybe partly cured goop helping raise the number a bit but I suspect torqued nuts would produce significantly higher numbers.
      You’re likely right on the money with your thought process

    • @Kirillissimus
      @Kirillissimus ปีที่แล้ว

      You only really need an activator in 2 cases:
      1) If both the screw and the nut are made of alluminium or other unreactive metal or plastics. I tried plastic screws into alluminium and the stuff just stays liquid for days and does not cure at all.
      2) If you need it to cure as fast as possible especially for zinc of stainless or if one of the surfaces is active but the other is inert. If you need it to operate right away though then split lock nuts are your friends as the bonding compounds need at least a few hours to cure even half decently even in best case scenarios.
      In any other case the activators are not very useful.

      I agree with your recommendation. I'm not a chem or materials guy, but from what I've heard about bonding details... 🤯
      Some adhesives work on a molecular level such that if you have more than _a few molecules'_ thickness of adhesive between the parts, you're not going to get the desired bond.
      I think epoxies would _not_ be in this group, as they stick to both parts _and_ provide a rigid gap filling material (also like the hot melt used for cardboard boxes)

    If the nut is loose, won't there be a bigger gap between the sides of the threads, compared to if it's torqued down? It might not be a representative test. It's like testing glue with a 1 mm gap

    • @blipco5

    Dear fellow Gear-Heads,
    I owned a national fastener distribution company for 26 years, AND I was a direct distributor of Loctite's Automotive Division products. As many have suggested, the fasteners should be tested under proper load. The #1 reason for fastener failure is improper torquing (under & over). The bolts and nuts should be paired properly according to their "grade", and even plating (in this case "Zinc", which is not only soft, but also acts as a lubricant) affects the torque range.
    By design, the assembly is meant to stretch, which slightly deforms the threads, especially on the nut. (This is why you should not reuse them, especially the nut. By the 3rd-5th properly torqued reuse, the threads can be completely compromised without you even knowing it.)
    For this test, there is an additional reason for torquing the assembly.
    As others have said, anaerobic thread-locking adhesives cure when oxygen is not present. They are specifically formulated for the tight tolerances between metals, especially under "load", where the least oxygen would be present. This is an important feature.
    Occasionally, we would have auto mechanics complain to our company that the thread-locker tubes they received from us were only half full. This is by design. The adhesive requires a certain amount oxygen in the tube, or it would harden and destroy the shelf life, if any. (So, store it "flat" to expose the most adhesive to the most oxygen in the tube.) Also, unlike some of the other methods of catalyzing, this adhesive doesn't cure in a uniform manner. The strength between those torqued threads will be much higher than any adhesive exposed to air on the assembly. (If practical, you could help insure the curing by applying heat [120 F+ if memory serves me] to the area which will dissipate the oxygen, though it shouldn't be necessary.
    Adhesive that falls outside the tight fitting metal surfaces , doesn't cure completely and can be wiped off and cleaned up.

    • @HacksbyDad
