I need some fasteners. One side has a very short male machine thread post, like 1/16" or 3/32", and a mushroom head with a Phillips or hex slotted head. The other side has a female receptacle of the same depth and thread, and the mushroom is unfinished. They are to put on Plexiglass panels, or to mount Sentra board graphics.
Anyone know what they are called?
