Screw backing out in spite of loctite

[Zed82]

I applied a bit too much loctite on a screw thread which landed on the inside of the link. The link became stiff of course which loosened up after a couple of weeks. The problem is that the screw now has backed out a little bit as it seems.

When i tightened it, it was standing on 9 and 3 o' clock. Now it´s on 12 and 6 o' clock. When i move the link i can see the head of the screw turning as well.

I don´t really feel comfortable in bringing out the screwdriver again. Do you think that i have to?

I'd heat the link (just over 200C will do for 221), remove the screw, clean it up and put a little 221 (8.5Nm) or 222 (6 Nm) on the inside of the link thread not the screw thread.

If the screw has loctite on the shaft it can bind to the link and do exactly what you see.

Yeah, i understood that i could apply the loctite only to the hole after it was all finished.

Guess i´ll have to do that.

Which loctite did you use?

Actually it wasn´t Loctite since it was very hard to find. It was an another brand thread locker. Guess it was a bit stronger then 221/222 but not a permanent lock.

The thread locker has glued the screw to the inside of the center link instead of the threaded hole.

Remove the screw, clean everything with acetone, apply thread locker only to the screw hole (as previously mentioned) and tighten.

Good luck!

Thanks. Tried that but the screw wouldn´t budge. It unscrews fully but it´s glued to the center link just like you say. The screw looks like a mess now and will need to be changed. Going to let my AD do the job.

I feel your pain!

Years ago I boogered up a screw head in my Submariner band and had to use a Dremel cut-off wheel to cut a new slot.

It ruined the link but I had an extra; still, I learned to be real careful with those little screws.

Good luck!

Ouch!

Actually it´s not that terrible looking but i´m quite OCD about it and don´t want a screw to show signs of wear at all. The bad luck is that it´s the screw closest to the clasp and the link has no hole underneath so i can´t use anything to push the pin out.

Yeah well, i´m going to let this be a lesson.
