The .pdf says "Close the mount and drive the m4x50 screw through all three pieces and secure on the backside with a nut." I don't see anywhere to secure a nut, also the M4x50 is extremely long for the hole. I don't see anywhere to secure a hex nut inside the latch, and the hole inside does not go through. It is completely solid on the other side. Not sure how I'd secure the button in there, has anyone remixed this or figured this out? apologies for the 'tism on this..
Ive also tried an m4x35mm, like the text on the hinge latch itself says.. and still too long for the button hole to secure. Also doesn't seem like it's a "one-time" thread in the plastic type hole either.. its as wide as the m4 with zero grab.
