M4 x 6mm
Sorry don't have any

My local super hardware shop has got the M4 countersunk hex drive, but only in stainless, & the shortest he does is 12mm so will need cutting down
He also has the M3 for the top screw again stainless only, & needs cutting to length.
The princely sum of 20p-ea for the M4, 12p-ea for the M3.

I'll be going that way on Thursday if you want some, it's the other side of Exeter about 10 miles away.

Thanks for the offer @angrybear.  I found the sizes and had 20 of each delivered today from GWR fixings.
