I would like to know what the hardware in question is called. It looks basically like a Chicago screw but is made out of one part. It's used a fastener on adjustable vintage leather straps. I have looked everywhere I could think of and haven't found it. It looks exactly like a Chicago screw but it's made out of one piece and neither head has a slot. If I know what's called I might find it. If I can't find this hardware, I might end up using a Chicago screw but I;'ll have to glue the two parts securely together with epoxy on the threads. I'd prefer using the one-piece hardware,
