Just to continue this slight thread drift. I purchased both metric and imperial 1/4" square drive Allen (hex) key sets. Ball end versions are available that work at modest angles. These are particularly useful where an access hole is not aligned with the bolt head. I'm thinking of course of the overrider lower screw innocent

Either type make work on socket head bolts so much easier though.
