Can Someone Help Toyota Provide Part Data

I am trying to find the thread/pitch for the clutch bleeder screw on a 2009 Tacoma 4WD 2.7L 5 speed manual extracab truck. Toyota it appears didn't even provide this in the parts databases, so dealers can not help and the Toyota customer service center says something like "you must (pay big money to) bring it into a dealer for a thorough analysis."

In my case, I am trying to get not only part number, but thread/pitch data so I can replace it with a speed bleeder.

It was actually humorous the whole experience contacting them, as I received mostly disclaimers and cautions. Almost seeming like what would be expected if I were contacting them about legal or medical advice or something.

 

Why not just undo yours and measure it?
Also what is the benefit of a speed bleeder for this? It isn't like you are going to be bleeding the clutch cylinders on a daily basis...
