Correct wrench to disassemble the M9 pommell screw

[Carlo]

After many years, I finally realized the the european wrenches have not the same size as the US ones.
I have problems to find the "correct" wrench to remove the M9 pommell screw.
All the wrenches I have here, seems too small or too large...I can unscrew it, but it is not an easy task, plus it damages a little the screw itself.
So, could someone please tell me the exact US size (i.e. the "numbers" I should look for) of this wrench, as long as the best manufacturer of it?
I will then try to look on ebay.
Thanks!

Carlo,

You need a 3/16" Allen wrench. It is a very common tool. You should be able to purchase one locally at a hardware or tool store.

Thanks!
Yes, it is a common tool here as well, but I have yet to find one with a perfect fit for the pommell nut.

After some research I can confirm that there is a difference between the english/imperial and metric wrench size.
A 3/16 inches wrench is equal to 4,76 mm.
European wrenches available are (among others):
4, 4,5, 5
Here is the reason my wrench was damaging all the screw: the 4,50 mm wrench is not equal to 3/16 inches (=4,76mm), as it is a little bit smaller.

Oh man, I already bought my US 3/16 wrench on ebay and I completely forgot about the two other screws of the cutter plate and the ones of the scabbard back strap, which are smaller. :frown:
Bill, could you tell me, also, which is the correct wrench for them?
Thanks! :wink:

The cutter plate screws use a 1/8" allen wrench.

Thanks Bill!
Fabrizio, didn't you have the same problems with the screws, there in France?
