I might be looking for an E8 spanner, the point to point is 7.5mm. Would I get away with an 8mm metric spanner/socket on this small head size.
The bolt is an M6 x 25mm.

Once removed, could be replaced with a flange hex screw with a 10mm hex head.

Might just "push the boat out" and get a set of these. (Silverline 241501).
