Screw backs have also got another term which is "threaded back”. They are named as threaded backs because the post is threaded and the back screws on it. When we talk about wearing a pair of earrings, we always need a piercing, but with the help of screw backs you can wear earrings without piercings. A screw back is a flat padded end which tightens the earring against the earlobe. It is similar to a standard post but the back actually screws on to the post.
