...or should I say, actually, I stripped a back-ring retaining screw's threads in the back of my Ti Zilla. :shock:

After I decided to change Walt's adapters from his springbars' to the Zulu's fixed ones, I overtorqued one of the screws and now the little rascal is all but semi-threaded onto the watch head. The other screws are firmly fixed, but the odd one screws like crazy -ouch!- and seems to be about to fall, although it does not - not yet, it is.

Question for the brethren: how would you go about it? Evidently I don't want to loctite the screw in permanently, nor I'd like it to go astray, and therein lies my problem.

Any and all help will be GREATLY appreciated!

Cheers and TIA,

Marcello GT

Two options I see take it to a watch repair and have the screw replaced with one maybe .1mm or .15mm bigger or use blue loctite instead of red if you don't want that super firm hard to remove screw.Blue loosens up quicly with heat from say a hair dryer.;)

Thanks for the speedy and helpful return, SD!

The watchmaker route may very well be the safest, and your suggestion re the larger screw -pun unintended- would bear witness to that.

However, I live in Brazil and although there are plenty of so-called 'watchmakers' around, I have yet to find one so apt that I'd trust it enough. Not to mention the many difficulties in securing the parts needed.

OTOH, your final suggestion seems quite interesting; what is the product number for the loctite you mentioned?

TIA yet again,

Marcello GT

I'll do one better here is the webpage for the 3 colors. Just in case others are wanting to Loctite anything.

Gives a brief decription and the part number is there. Then just google around for the best price unless you know of a local place that sells it.

Here in the states you can find it in many hardware stores and might even find it in your local Walmart.

Just a quick update, fellows!

I've yet to receive the "weaker" Loctite (#s 221 and 222) and decided -for the time being- not to apply any nail polish or another such alternative to avoid clogging the screw and the threads in the watch.

In the meantime, I'm wondering how to clean them AFTER applying the Loctite, say, if something goes wrong or whatever. If anybody has something to say, I'll appreciate it!

Cheers to all,

Marcello GT

Just a quick follow-up, fellows!

The thread lockers finally arrived and, although I couldn't secure the Loctite #221 or #222, I found their closest relatives from another company.

In spite of that and somehow to my chagrin as well as relief, it all proved unnecessary. As I again disassembled the watch back-ring to clean and prep the threads and screw, I noticed a couple of small metal shavings lodged at the bottom of the thread as well as on the side of Walt's adapter. mistake.gif

Close examination revealed that the shavings came from the adapter itself (not the watch!) and that the screw had either cut them off or simply dislodged them from the adapter bearing surfaces. I huffed and puffed and blew and rechecked everything before attempting reassembly, sans thread locker.

Well then, the offending screw threaded perfectly and firmly. Of course I paid extra attention to not overtighten anything, but that little rascal is set! At this point I've chosen to put aside the thread lockers in order to use the watch a couple of weeks and verify the torque at the end. If the screws are OK, I will end up with an ample stock of thread locker on one hand and a very valuable lesson on the other.

Thanks to everybody who chimed in, I learned a lot more about thread locking compounds than at first thought possible. 'Appreciate it! hand6.gif

All the best,

Marcello GT
