Odd sized hex bolts on Defender - Imperial ??


Discussing the external rear view mirror arms (with the spring loaded rotational mount at the door hinge end and the ball at the mirror end).

I need to remove mine (removing to repaint after corrosion removal) but the hex socket (underneath the plastic insert) has a measurement of 7.7mm between flats

Looking at an fractional imperial to metric chart I see that this measurement sits between:

5/16 @ 7.94mm (too large) and 19/64 @ 7.54mm

I don't have a 7mm hex key, but suggest it would be too small anyway, so is 19/64 a common hex key size ? And why would LR do that ?

Removing the whole lot (door hinge etc.) and masking the joint for painting it is an option, but I'd rather just go direct if possible.

What am I missing?

I don't think that is a hex screw. The one on mine is a crimped piece that does not unscrew, The crimp looks like a hex screw, but it isn't.
