My EM only has three visable screws in it I used SS allen socket countersunk screws in SS finish washers.I was concerned about the finish washer cutting the fabric ,so I glued a ss flat washer to the back each of the finish washers .It spreads out the force applied to the fabric.If there is a rounded edge to the fifnsh washer put it towards the fabric. most washers are stamped(punched from flat sheet stock) leaving sharp edges on one side ( inner and outter ) and a rounded edges on the other . I had seen a manufactured washer like I made on a piece of equipment from Australia. My brother showed me screws for some aircraft . They had the washer incorporated onto the screw.It was for a metal surface and ended up almost flush.
