Question about Loctite
Greetings Fellow TRFers:
Quick question regarding Loctite. I’ve been reading how it’s important to heat up a link you are about to replace so the Loctite melts and you are able to unscrew the screw with ease. My question is this: if you’re heating up a particular link, won’t the adjacent links also get heated as well and hence melt the Loctite in the adjacent links? Will the Loctite thats heated in these links eventually harden again when it cools down? The worry of course is if it doesn’t harden again and your left with some links without the safety of Loctite? Just wanted some insight. Thanks! |

Question about Loctite
If it melts, it will harden again when it cools, which is quite fast. But it shouldn’t be too difficult to hit just 1 link with a lighter flame. Hope you’re not using a flamethrower

I just put my watch in the oven at 200c for about 30mins (or until it gets a little golden on the top) then I know the links will unscrew real easy. It's nice with a little potato salad also.

I don’t think it hardens again Nick.

Eh hem... mmm-kay gentlemen.
Yes, you want to warm it up a bit and then you'll be fine. It is 'minor' Loc-Tite Rolex uses. See this link for more data / details http://henkeladhesivesna.com/blog/th...threadlockers/ NEVER use Loc-Tite RED unless you never want the bolt to ever come loose (though 550F will if fact aid in removing something where RED was used). Hope this helps.

Loctite 222 is the preferred type. It is the "small screw" type designed to be the easiest / least "locking" type to use. Anything stronger and you are 'screwed' so to speak.
And apply just a touch to the female threads only, NOT to the pin threads. Otherwise the Loctite gets transferred onto/into the bracelet links when you insert the pins into the links.

^^^This needs to be said again. Just a small amount of the purple thread locker in the hole is all that is required. Do it the other way around and your link will get stiff and rough feeling. |

Thanks for the input and the humor, fellas.
What do you recommend I use to apply the Loctite to the female threads? Would a toothpick work? Is it fairly easy to see/get to the female threads? |

You can drop the Loctite in the threads at any time as they are only on one side of the link and extend through the link - you can see them. Loctite is an anaerobic and only hardens after a lack of oxygen when the threads are mated up.

If you are unfamiliar with Loctite, you should probably only use it with a friend.

Just a follow up: it seems one of the screws in my bracelet is rotating in place as I move the adjacent link from one side to the other. It doesn’t seem to be unscrewing, however, but rather, saying in place.
Is this normal? Lol |

The screws should stay aligned with the link they mate with.
They only screw in until they lock on their shoulder.

The screw-bars are simply studs that screw into threads. There is no shoulder or clamping edge to tighten these studs against, they simply bind into the thread base when fully tightened. If you force them, you can literally jamb them into the female threads of the link, cracking the root. Since the stud is already loose, take it out and smear a bit of lithium or silicon grease on the shaft, then screw it down tight (but not too tight) until you have access to the proper Loctite.

Wow thank you for the insight. I know this has been mentioned before but what screwdriver do you recommend for a modern ceramic sub?
Any particular kit with considering? |

Horotech makes a nice screwdriver, but there are many others too.
Most advocate for a hollow-ground tip, but if it isn't tight, most screwdrivers will do the job without damage if you are careful. Rolex Oyster bracelets are 1.6mm heads. Here is a hollow-ground screwdriver tip and how it is shaped. hollow ground.jpg

As an added bonus, since the driver is small, it’s very difficult to over tighten a bracelet screw.

A good way to remove a link if it won't easily unscrew is to use a butane cigar lighter which has a very narrow flame and can be held on the threaded end of the object link without overly heating adjacent links.

This is where the screw locks on the link.
