Easy to use hopefully it will keep bolts from coming loose every few weeks to months. Sit far it’s looking good.
I have only rated this a 4star because I haven't tried to remove my Slider pin Nuts /Bolts which is what I used this product for.Am relying on reviews I read about this product holding bolts in place, while being easy to unscrew bolts when needed.
Does what it says on the tin. The gold standard for threadlocking with good reason, it just works.
I bought this stuff along with 4 bolts a month ago to replace the bolts on the base of the stem of my electric scooter, which were loosening repeatedly and making riding extremely dangerous. This stuff has worked a treat. I applied it generously to the threading of the bolts, screwed them in tight, left it to dry for 24 hrs, and have no had to tighten them since. Excellent product!
Great product, changed the knobs on my fishing reels, knobs kept winding themselves off, added a dab of threadlocker blue, no issues since
Great product. Needed it to bolt a few things down but also be able to take apart when needed
Bought to tighten a folding door Hing screw that keeps coming loose.After applying Loctite it hasn’t loosen
