High strength thread locker.
Had a problem in removing a thermostatic shower valve as the body was unscrewing leaving part of the valve in situ and impossible to remove. Used red Loctite to fix both parts together enabling both parts to unscrew together, thus fixing the problem.

Very Strong Bond
Very strong chemical resistant bond if the manufacturers instructions are followed. Just be sure you don't want to take it apart again.

It doesn't work
**Did not work as expected**Very disappointed with this product. The thread locker was extremely thin and had an almost water-like consistency, which didn’t seem right. I applied it as directed, but it failed to hold the thread securely and the fastener still came loose. Expected much better quality and performance from Loctite.

SAVAGELY STRONG - Do not worry about anything coming loose
★★★★★ Small bottle, absolutely savage bondBought this to attach the eye bolt/hook on my magnet fishing rig to the magnet body, and it turned out way stronger than I expected from something this small. The application process itself is dead simple — clean the threads with rubbing alcohol, degrease, drop a few dabs in, thread it together, and let it sit.The cure time is the part people skip and shouldn’t. I gave mine a full 24 hours before touching water with it, and the difference is night and day compared to rushing it. Once cured, this stuff locks in like it’s welded — no shifting, no loosening, nothing.I’ve pulled some genuinely heavy stuff out of canals and rivers with this rig since — bikes, chains, random scrap metal — and the bond on that hook hasn’t budged a millimeter. Given how much force gets thrown through that eye bolt when you snag something heavy and yank hard, that’s a serious testament to how strong this hold actually is.Only thing worth flagging: a little goes a long way, so don’t overdo it thinking more equals stronger — it doesn’t, and it just makes a mess. Additionally, i added a thin superglue layer above because this stuff dries WITH THE ABSENCE OF AIR.Overall, this is the cheapest insurance you can buy against losing your hook (and whatever you just caught) at the bottom of a river. Zero regrets, and I’d recommend it to anyone building or maintaining their own magnet fishing setup.
