Help with allen key size for tele bridge saddles, please

[Bob Gnarly]

Smallest key I have is 1.5mm and it is too big.
Local hardware store sells a set that has a 1.27mm but I can't try before I buy.
Does anyone have the same style bridge and know the size?
It's a Mexican Fender

USA Fenders use a fifty thou allen key
0.050" is how you'll see it referred to usually.

Great, thanks. That equals 1.27 mm according to google, so that set at B&Q is a go. :D

yes 1.27mm is the metric equivalent size
