Screw back earrings are characterized by their secure screw design. The post features a threaded design that screws into the earring back. This allows you to screw the earring into your or your child’s earlobe without having to push it into place.
The name, ‘screw back earring,’ gives away its mechanism. Screw-backs will always have a screw and a threaded post. While it takes a lot of patience to screw the back into the threaded post, it is one of the safest mechanisms to keep your earrings from falling off.
