Shimano shifter/brake bolt replacement

[locoboy]

Hi, Not Orbea specific I'm sure but it is on an Orbea so thought it worth posting here.
Can anyone Identify the type of brake/shifter fixing I have on this shimano combo? I've herd of matchmakers, I-spec etc but not sure what this one is. I need a new bolt - circled in green.
Thanks

Nothing special about the bolt itself. Just measure the width and replace it with something the same length. I have a box of bike bolts that i keep for such use. Even your local hardware should have something suitable, maybe with a different head.
