I have finally re-sized this bracelet (damn those tiny screws!), and I understand the bracelet screws should go back with a mild thread-lock compound.

So I chose Loctite 222 purple for small screws, no heat needed for future un-doing. But my question is: do you put a tiny amount on the screws...the screw hole...does it matter? And do you just use the tiniest bit on a couple of threads, or make sure every thread is covered? Many thanks for sharing you expertise/experience.

 

I just put a small dot with a pin on the screw thread. As you turn the screw, it will spread throughout the thread. Honestly though, it's not as crucial as say on a Rolex where a lot of tension is put on each pin. These Omega screws just hold in the center pin which takes all the abuse.

 

I've never used loctite on watch screws. That being said when I've used it elsewhere I use a small drop around the middle of the threads and then simply screw in and torque to spec. I wouldn't cover every thread, would get messy.

 

Place a small amount on the first couple of threads, then screw the screw all the way in, unscrew it all the way out, and then screw it down. If you read and follow Loctite instructions, this is how they tell you to use it. Remember the more you add, the greater the holding power will be. You don't need a lot.

Cheers, Al

 

Thanks, Al. I'm guessing you are referring to the threads on the screw, not the threads in the bracelet, is that correct?

 

Yes

 

Much appreciated.

 

Am I the only one who thinks it's a bad idea?

It is a bad idea unless you know what you're doing. Most people usually end up putting too much which actually attaches itself to the non-threaded part of the screw and can actually help to unscrew the screw easier on its own or seize up the link. Then there are the ones that use the wrong type of Loctite and strip the head when they try to adjust it again.

 

I've been wearing a 300 since it came out and I've also taken out a few links. I've never had a problem and never used Loctite.
Please do not use Loctite

 

Good points. Since the screw is just really a cap here, I guess the goal is to just put enough on so that vibration doesn't work it loose. I'm going to err on the stingy side with how much I apply.

 

Well it comes from the factory already with Loctite but it should be fine without it

 

If you know how to use it, Loctite is perfectly appropriate here. Please do not use it if you don't know how to use it properly...

 

I have been trying to get mine sized and now I fear I have stripped a couple... this is rediculous, never have had a problem with screw bracelets before from , Rolex , Tudor , even Omega aqua terra bracelets

 

Stripped trying to get them out...putting them back? Are you using the proper screwdriver size?

 

You have to use the proper screwdriver size. That is most important. Then, you have to push in firmly while screwing/unscrewing to ensure it doesn't slip and scratch everything. The flathead slit on the screw is really shallow and a much softer metal than Rolex/Tudor uses.

 

Is the proper size for most of Omega's bracelet screws (or at least for the SM master 300, 1.8 or 2.0 mm? Thanks.

 

Some came out moderately easy ... others seem impossible
I am going to get the big daddy torch out tomorrow...

SCREW M1.40 ØH1.9 L1.8 STEEL

Head diameter = slot length, so 1.8 would be appropriate here. Make sure the screwdriver blade is properly fitted to the slot...
