Is this the air tank drain plug?

If so, is that a 5mm allen socket? Mine is starting to strip, so I'm pausing until I get some feedback.

I have had a few issues with those smaller allen key type sockets all over the Rush. My standard "Craftsman" sockets are just NOT up to the job with the car. Basically the torque specifications on the small stuff will snap the Craftsman or round the nut. I FINALLY bought my first SnapOn tools for this stuff (Ball head metric). However, what I have found far better is the Proto Advanced Metric set. They aren't cheap, but not quite SnapOn cost, but they don't tend to strip the nuts like the other units and will handle the torque specifications. IMHO, this should be on the "Must buy" list of tools. I got from Grainger...
