Kev,

I don't understand "Is the Febig box pic relative".

As for TYG000260, this bolt is completely different from TYG000250.
TYG000250: M10 x 1.5 x 50mm with a threaded portion of 40mm and a full shank diameter over a length of 7mm. The flanged bolt head suits an E12 socket.
TYG000260: M10 x 1.25 x 60mm with a threaded portion of 28mm and a full shank diameter over a length of 30mm. The flanged bolt head suits an E12 socket.

They aren't the "same bolt" at all.
