I am attempting to mount a pair of 2402H tweeters on the back of a 1.5 inch thick baffle board. I routed out the baffle surface to coincide with the angle of the horn launch. Getting inside of this enclosure to mount a different type of screw from behind is a non starter. (The enclosures are already built sanded and the back is sealed, it is tight in there)
I guess the best way to do this is to form a template so i know exactly where to drill the holes for the 2 inch long machine screws. Now, the 10 cent question:
What is the size and pitch of the threads on the mounting flange of the 2402H's? Everything i tried at the hardware store would go in about 1.5 turns and then become locked. I don't want to "bugger up" the threads nor drill and retap.
What the devil are they?
Thank you so very much in advance for the workable answer.

Short of taking the actual driver in to the hardware stores, I went to Lowes and purchased 16 different machine screws. No one there that i talked to knew the difference between a machine screw, a wood screw a cap screw, bolt or self tapping. I was amused when i was shown sheetrock screws after I explained exactly what I was trying to accomplish!
