I agree with RJ, measure from outside of the track to get the depth of the stud. Because as you tighten down the stud it pulls the stud up to flush with the track. Studs arent a exact length they add extra length already.
My track is roughly between 5/8 and 3/4 measuring outside of the track. And I put 1 inch studboy gold diggers, and they exceed my track by 3/8 inch almost. OOPS on my part, I was a newb at the time.

And they are aggressive as heck. Almost wish I put 7/8 inch studs in, might of improve ride on ice.
