GC1111's observation may be correct. What I related referred to a "similar" looking wheel but from your snaps, I cannot be sure. Unfortunately, we also have some fasteners aboard our boat that require a 6-pointed "star" shaped driver. While a superficial inspection gives one to believe the fasterers require an Allen Wrench, they actually require the star-shaped drive. I bought a full set a Lowes--from 1mm to 10mm--for around $15 (USD) during one of their Sales and this may, in fact, be the drive you need.

Reason: correct typo.
