I recently installed a Badger M5 and was wondering how much thread engagement people are getting with theirs. My rear action screw tops out at exactly 3 full turns after torquing it down and the front screw is at 2 full turns. The rear tang has quite a bit of thread left exposed so it seems a bit short, but my screws measure 1 3/8" and 1" for the length of the threading which seems pretty normal.
