New here - hope this is the right place to post!
I am refurbishing a leather sling Bruno Mathsson for Dux Jetson chair from the 1960's. I have a quilted seat cushion attached to the leather sling of the chair via standard steel grommets with a 3/8" hole. In order to attach the grommets to one another, the chair had some sort of Chicago Screw that secured them. I only have 3 of these, but am needing a total of 12.
I don't mind straying from the original, my only trouble is that I need something with a head of 12-14mm, which has been absolutely impossible to find. I am attaching images of the original screw - a sort of tunnel with serrated edge. Is this even a Chicago screw? Or some sort of screw grommet? All assistance is appreciated!
Thanks!
