I need a replacement grub screw for a door handle (okay - I don't need

It is a fairly new door handle so I assume it is metric. Is M2 so
small as to be excludable? I assume it's 'cup point'. Thanks.

Can't you measure the existing one, or at least guess its size.

The M sizes are simply outside diameter in mm.

That was the missing link! I have measured and it will be M5 or M6 so
I will just order up the pack of 40 assorted. Thanks for your help.
