The thinner K-N screwbutton nuts allow Sanwa OBSN-30 screwbuttons to fit into a MadCatz TE. The joystick mounting brackets get in the way of Sanwa OBSN-30 screwbutton rings, which are bigger than the K-N.
Buying a couple of these will save you a headache if you're installing Screw On Sanwa buttons for your arcade stick. These screwbutton nuts are smaller than Sanwa's and will allow to fit all of you buttons on your stick. Buy before you check out!Javier
