39mm Fork Damper bolt size

[Watson]

Rebuilt my front end last night, and after completely assembling the first fork, I realized that the second Fork Damper Bolt was missing. I could always drain the oil out of the other one and take the bolt to the hardware store, but I thought I would ask first here...Anyone know the thread type for a 2001 sportser 39mm fork damper bolt? As in, the one that goes into the lower through the axle space? Would save me a bit of a headache.

Metric threaded bolt. Go to a dealer to get one, hardware store not likely to have the right one. I think part number is 45405-75A
