Panerai Lug Screw size or Tap Size

[blackbard]

I have spring bars...They work great...

Ok, now thats out of the way...I would like to know what the screw size is or what tap I need to clean up some marred threads on the case.

I'm sure there is a tap to fit, just dont know the size. Any assistance in this area would be helpful.

I posted in the repair forum, but it may not be a frequently visited, and this team is comprised of expertise...

Thanks!

I posted the same question back in May. I ended up purchasing an assortment of very small metric taps. Had no sucess, as the threads were tapped from the band side of the lug, and it is very difficult to start to chase the thread from the finish side, as mine were buggered up from the shop drilling the lug part way for the screw head recess. by mistake. I could get it started in the good lug side, no problem. If your threads are messed up on the band side of the lug you may be OK. I ordered the taps from Micro Tools, I also posted a link to the in a previous post. I'll see if I can find the taps in my box and then give you the size that worked.

Ok, you are going to force me to search? No link?

And you're going to force everyone else to search?

Of course not:

Thread end diameter: 1.28mm measured with digital calipers 3 times...Need thread pitch...

I don't think thread pitch exists when you are dealing taps this small. UNC, UNF, UNSF are out the window and this size.....could be wrong.

Ok. Also, they come in 1.3mm so with tolerance....That should work no?
