The short answer
Earring backs come in four common types: friction (push) backs, screw backs, lever-backs for dangle earrings, and locking backs for higher-value studs. A lost friction back is the easiest fix, universal rubber or metal push backs sold in multi-packs fit almost any post diameter for a few dollars. A lost screw back is trickier, since the threading has to match the post exactly, so a universal screw-back multi-pack (sold with several thread sizes) is the practical fix rather than hunting for the exact original part. If you don't know which type you're missing, check the remaining earring in the pair, that's the fastest way to identify what to buy.
Losing an earring back usually doesn't mean losing the earring, most backs are a standard part sold separately in multi-packs, and the fix takes minutes once you know which type you need.
How to Figure Out Which Type You're Missing
The fastest way to identify a lost earring back is to look at its surviving pair, the post shape and remaining back tell you everything. A smooth, straight post with no visible ridges takes a friction (push) back. A post with visible spiral grooves running down it takes a screw back, and the threading has to roughly match the post's diameter and thread pitch to stay on securely. If the earring is a dangle or drop style with a hinged wire built into the design rather than a separate small part, it's a lever-back, and there usually isn't a separate 'back' to lose in the first place, so a missing closure usually means a broken hinge rather than a lost part.
Where to Buy Replacements
Universal multi-packs (sold as "earring backs, assorted" or "earring backs replacement pack") cover the two most common losses, friction backs and screw backs, and typically include several sizes in one pack for a few dollars, which is the practical fix for almost anyone who's lost a single back. If the earring is from a specific brand and the back has a proprietary shape (locking mechanisms in particular), check that brand's website or customer service first, a universal part may not seat or lock correctly. A local jeweler can also often supply or solder on a matching back on the spot, which is worth it for a single valuable piece rather than an earring you'd otherwise replace.
Preventing the Next Lost Back
Screw backs are inherently more secure against loss than friction backs, since they have to be deliberately unscrewed rather than just pulled or bumped loose, which is why they're the more common choice for studs meant for all-day wear. For friction backs on earrings you wear often, a slightly tighter, higher-quality rubber back (rather than the thin stock metal disc some earrings ship with) meaningfully reduces how often you lose one, since the softer material grips the post more consistently through a full day of movement.
At a Glance
| Back Type | How to Identify It | Best Fix | Typical Cost |
|---|---|---|---|
| Friction / Push Back | A small disc or butterfly shape that pushes onto a smooth straight post with no threading. | Universal rubber or metal push-back multi-pack, fits almost any post gauge. | $3-$8 for 20-50 pieces |
| Screw Back | The post has visible spiral threading; the back twists on rather than pushing. | A universal screw-back multi-pack with several thread sizes, since exact-brand threading can be hard to match. | $5-$12 for a variety pack |
| Lever-Back | Part of the earring itself on a dangle/drop style, a hinged wire that clicks shut. | Usually not replaceable separately, since it's structural; a jeweler can repair a broken hinge. | $10-$25 jeweler repair |
| Locking Back | A back with a small lever or spring mechanism designed to resist coming loose. | Brand- or style-specific; check the earring manufacturer for an exact replacement first. | Varies by brand |

Where can I buy replacement screw earring backs?
Universal screw-back multi-packs, sold online and at most drugstores/craft stores, include several thread sizes in one pack since exact-brand threading can be hard to match without the original manufacturer.
Can you buy just the backs of earrings?
Yes, for the two most common types (friction/push backs and screw backs), universal multi-packs are sold separately and inexpensively. Lever-backs and locking backs are more often structural or brand-specific and harder to replace as a standalone part.
What can I use to replace the back of my earring?
Match the replacement to your post type first: a smooth straight post needs a friction back, a threaded post needs a screw back of a similar thread size. A universal assorted pack is the most practical option since it covers multiple sizes.
Do screw-on earring backs come in different sizes?
Yes, thread pitch and post diameter both vary slightly between brands and earring styles, which is why a universal multi-pack with several sizes included works better than betting on a single exact replacement.
