Screw Back vs Push Back Earrings
Screw backs are more secure. Push backs are more convenient. For diamond studs you intend to wear every day, choose screw backs.
How each works
A screw back has a threaded post; the back turns onto it and locks in place, and cannot come off without being unscrewed. A push back, also called a friction or butterfly back, slides onto a smooth post and is held there by friction against a small notch.
Why push backs loosen
Friction weakens with use. Each time a push back is removed and replaced, the grip on the post eases slightly, and over months the back can loosen enough to slip off. This gradual loosening is the most common way a stud is lost. A threaded post does not loosen through wear in the same way.
| Screw back | Push back | |
|---|---|---|
| Fastening | Threads onto the post | Friction against a notch |
| Security | Higher | Moderate, reduces with wear |
| Speed to fasten | Slower | Faster |
| Sleeping in them | Suitable | Not recommended |
| Travel | Suitable | Higher risk of loss |
| Frequent changes | Less convenient | More convenient |
| Best for | High carat weights, daily wear | Lighter studs changed often |
Fastening a screw back without damaging the thread
Hold the post steady between finger and thumb at the front of the ear, then turn the back clockwise onto it. Let the thread catch on its own before applying any pressure. If it resists in the first half turn, back it off and start again.
Forcing a back that has not caught is what strips the thread, and a stripped post cannot be repaired — the earring has to be re-posted by a jeweler. This is the one failure mode screw backs have, and it is entirely avoidable.
Turn until the back sits against the earlobe without compressing it. Tight enough to stay, loose enough that the lobe is not pinched.
Post length and thickness
Standard earring posts are around 10 to 11mm long, which suits most earlobes. A thicker lobe may need a longer post; a very thin one can leave excess post protruding behind the ear.
Post thickness matters if your piercing was made with a thinner gauge. A post noticeably thicker than the piercing will not pass through comfortably and should not be forced. If you are unsure, measure an earring you already wear easily and compare.
Which to choose
Choose screw backs if the earrings will stay in most of the time, if you sleep in them, if you travel with them, or if they carry a carat weight you could not easily replace. Choose push backs if you change earrings often and always take them out at night.
A note for children and first earrings
Screw backs are often preferred for children's earrings for the same reason — they stay put. Check the post length suits the earlobe, and follow the piercer's advice on newly pierced ears.
If you lose a back
Replacement backs are widely available, but they are not universal. A screw back must match the thread of its post, and a push back must match the post gauge. A back that almost fits is worse than no back, because it feels secure while gripping on very little.
Until a correct replacement arrives, do not substitute a back from a different pair on a stone you would mind losing. If the earring is one of ours, contact us with the design and we will match the fitting.
Looking after them
Push backs should be checked from time to time: hold the stud and gently try to pull the back off. If it slides off easily, the grip has worn and the back should be replaced. Screw backs only need checking that they are fully tightened, and an occasional clean of the threads.
Skin oil and hair product build up inside both types and on the back of the stone. A short soak in warm water with a little dish soap, then a soft brush, keeps the fitting working and the diamond bright — our guide to cleaning diamond jewelry at home covers the method.

Common questions
Are screw back earrings more secure than push backs?
Yes. A screw back threads onto the post and cannot be pulled off without unscrewing. A push back relies on friction, which weakens with repeated use.
Can you sleep in screw back earrings?
Screw backs are the more suitable of the two for sleeping, because they cannot work loose through friction. Push backs are not recommended overnight.
How do I know if my push back is loose?
Hold the stud and gently try to pull the back off. If it slides off easily, the grip has worn and the back should be replaced.
Which back is best for expensive diamond studs?
Screw backs. The higher the carat weight, the more the extra security matters.
Can push back earrings be converted to screw backs?
Not directly. A screw back needs a threaded post, so converting means replacing the post itself, which is a jeweler's job and is not always worth doing on lighter studs.
Why does my screw back not turn onto the post?
The thread has not caught. Back it off completely and start again, letting it catch before applying pressure. Forcing it strips the thread and the post then has to be replaced.
