Fox 2.5 set screw size?

Does anyone know the size of the allen head set screw on the Fox 2.5 remote reservoir coilovers? The model I have has a single adjustment ring that is pinched around the threaded shock body by a single allen screw, so not the set screw that pushes into the threaded shock body.

Trying to do an adjustment, both of my set screws are facing inboard, so I want to make sure I have the right tools before I take everything apart to adjust the height. Since the screws are inaccessible, I'm going to have to pull the top end of the coilovers out and reposition everything. Shoulda done that when I installed them, but I was too excited about the new setup.

Cheers!

Ended up pulling the coilover and luckily I had the right allen wrench. It's 3/16" in case anyone else comes along wondering.

 

I just installed these same coilovers on my truck a couple days ago. When i first noticed that there was only one adjustment ring rather than the typical two ring design, i thought it was defective or something haha. I didnt know what to think about that.
How do you like them?
