Push backs and screw backs: watch the difference
A friction back slides onto a compatible post and grips it, while a conventional screw back turns onto a matching threaded post. Swapping random backs is not always a good fit, and neither style makes an earring impossible to lose.
What this lesson shows
Two different mechanisms.
The illustrated mechanisms show a friction back sliding onto a smooth, notched post and a screw back turning onto a threaded post, advancing one thread with each turn. The drawings are enlarged and simplified.
Three quick takeaways
What to actually do when you shop
- A friction back grips a compatible post; a conventional screw back follows a matching threaded post.
- That is why swapping random backs is not always a good fit. Neither style makes an earring impossible to lose.
- Check the match, the condition and how the back feels to use, and have a jeweler fit the right back when in doubt.

One earring back pushes on. This other type twists onto threads. A friction back grips a compatible post; a conventional screw back follows a matching threaded post. That is why swapping random backs is not always a good fit. Neither style makes an earring impossible to lose. Check the match, the condition, and how it feels to use. When in doubt, have a jeweler fit the right back. Explore more in the Aydins Jewelry Learning Center.
