Metal cylindrical screw on pin backs made for tie tack style pins with a post. This is a very secure pin back that uses a screw to hold the pin backing in place. To remove it or put it on a pin, you put the pin in the hole and then tighten or loosen the screw with the included little hex wrench. We will ship them with the screws in place, but be careful if you unscrew them all the way since the screws are removeable. Perfect for wearing pins on places that require a clutch with a good grip. Solid metal with a silvertone plating. Price is for one set of 10 screw on backs with one tool.
5 mm high.
