Threadless vs Threaded Jewelry: Which One to Buy for Your Piercing
Short answer: buy threadless. For most people and most piercings it is easier to use, just as safe, and more versatile than internally threaded. Internally threaded is a fine second choice and better suited to high-movement piercings. Externally threaded should be avoided entirely — that one is not a preference, it is a quality problem.
If you have ever shopped for flat back labrets, nose studs, or cartilage earrings, you have seen all three terms. They look nearly identical in photos. Here is what actually separates them, and what to buy.
The Three Types of Threading in Body Jewelry
All body jewelry with a removable end — a flat back labret with a decorative top, a barbell with screw-on balls — uses one of three connection systems:
1. Externally Threaded — The threads sit on the outside of the post. The post screws directly into the decorative end. Oldest and cheapest style.
2. Internally Threaded — The threads are inside the hollow post. The decorative end has a thin threaded pin that screws in. The long-running professional standard.
3. Threadless (Push-Pin / Push-Fit) — No threads at all. The top has a slightly bent pin that pops into the hollow post and is held by tension. The newest system, and the one the industry is moving toward.
Externally Threaded Jewelry: Avoid It
Externally threaded jewelry is what you will find at most mall kiosks, budget marketplace sellers, and cheap jewelry sites. The threaded grooves sit on the outside of the post — the part that passes through your piercing.
The problem: those exposed threads scrape the inside of your piercing channel every time the jewelry goes in or out. In a healed piercing that is minor irritation. In a healing piercing it can tear fistula tissue, introduce bacteria, and set your healing back.
This is why professional piercers refuse to use it. The Association of Professional Piercers specifically recommends against externally threaded jewelry for initial piercings.
Is it ever acceptable? Not really. Even for healed piercings, internally threaded and threadless are more comfortable and cost little more. External threading exists because it is cheaper to manufacture, not because it is better for anything.
Internally Threaded Jewelry: The Proven Classic
Internally threaded jewelry has been the professional standard in piercing studios for years. The threads are hidden inside the hollow post, and the decorative end carries a small threaded pin that screws into it.
Why it beats externally threaded: the outside of the post is completely smooth. Nothing catches or scrapes on the way through. That makes insertion more comfortable and meaningfully safer for a healing piercing.
The downsides: it can be fiddly. The threaded pins on the ends are tiny, often under 2mm, and screwing them in takes good dexterity and sometimes hemostats. If your hands are wet or oily, you can lose five minutes to a ball smaller than a grain of rice.
Threads also wear with repeated use, which eventually means ends that will not stay tight. Some people find internally threaded ends loosen gradually through the day, especially in piercings that move a lot.
We carry internally threaded jewelry in implant-grade titanium for people who prefer this system.
Threadless (Push-Pin) Jewelry: The Modern Standard
Threadless — also called push-pin or push-fit — is the fastest-growing system in the industry. Instead of threads, the decorative top has a thin pin that you bend slightly and push into the hollow post. Tension from the bent pin against the straight post holds it.
How it works:
1. Gently bend the pin on the top, roughly 10 to 20 degrees
2. Line the pin up with the opening in the post
3. Push it in — you will feel it seat as the bent pin tensions against the inside of the post
4. Done. No tools.
To remove it, pull the top straight out with a firm, steady tug. No twisting.
Our VitalFit™ Threadless System uses this mechanism in implant-grade titanium, in 6 sizes.
Threadless vs Internally Threaded: Head to Head
Since externally threaded is off the table, the real decision is between these two.
Ease of use: threadless, by a wide margin. Push in, pull out. No tiny screws, no tools, workable with wet hands or limited dexterity. Internally threaded needs patience and fine motor control.
Security: both are secure when fitted properly. Internally threaded ends can unscrew gradually with movement, particularly lip and tongue piercings. Threadless ends do not loosen over time because the tension is constant — but a pin that is not bent enough can pop out.
Versatility: threadless. Any threadless top fits any threadless post of the same gauge, so one bar can carry dozens of tops. Internally threaded requires the thread pitch to match, and it varies between brands.
Safety: equal. Neither has exposed threads. Both slide through the channel smoothly.
Comfort while worn: essentially identical. The difference is during changes — threadless means less time handling jewelry next to a sensitive piercing.
Durability: slight edge to threadless. Internal threads can strip; a threadless pin can simply be re-bent when it loses tension.
Price: comparable at the same quality level. Compare our threadless jewelry against our internally threaded jewelry.
Which Should You Buy?
Buy threadless if you want the easiest jewelry to change yourself, you swap tops often, you have several piercings and want one system across all of them, you find tiny screws frustrating, or you are new to body jewelry.
Buy internally threaded if you prefer the locked-in feel of a screwed connection, your piercing is in a high-movement spot like a lip or tongue, you already own internally threaded pieces you want to match, or your piercer recommends it for your placement.
The trade-off, honestly: threadless asks you to get the pin bend right. Too little and the top can come off; too much and it is hard to remove. It is a five-second adjustment you control, but it is a thing you have to learn. Internally threaded asks nothing of you except dexterity.
What Actually Goes Wrong When People Buy Threadless
Two mistakes account for most of the threadless problems we see, and neither is about the system being bad.
1. Buying tops without posts. A threadless top is only half the jewelry. It has no back, no bar, and nothing to hold it in your piercing. We have had orders arrive with seven decorative tops and not a single post. If you are starting from scratch, you need both — the top you like, and a flat back post or bar in the right gauge and length.
2. Mismatching the gauge. The pin on the top has to match the post. An 18G top will not seat properly in a 16G post, and a 16G top will not fit an 18G post at all. If you already own posts, check their gauge before buying tops.
Both mistakes cost you a return and a second order. Both take thirty seconds to avoid.
Understanding Gauge and Compatibility
Whichever system you choose, the top has to match the post:
Threadless: pins come in 20G, 18G and 16G. 20G is for earlobes and nostrils only — cartilage needs 16G. Match the top's gauge to the post exactly.
Internally threaded: the threaded pin has to match the thread pattern inside the post. Quality jewelry uses the standard pitch for each gauge; cheap jewelry sometimes does not. Buy from sources that state their specifications.
For gauges and lengths by piercing, see our sizing guide.
How to Insert and Remove Each Type
Threadless (push-pin):
Insert: bend the pin slightly, roughly 10 to 20 degrees. Hold the post steady against your skin. Push the top in until it seats and feels snug. Give it a gentle tug to confirm.
Remove: hold the post steady, grip the top firmly, pull straight out with even force. Do not twist.
Tip: loose end? Pull it and bend the pin a little more. Too tight to remove? Straighten it slightly. You control the tension.
Internally threaded:
Insert: hold the post steady, place the end against the opening, turn clockwise until snug. Do not overtighten — you can strip the threads.
Remove: hold the back steady, turn counter-clockwise. If it is stuck, latex gloves or clean hemostats give you grip.
Tip: if an end keeps working loose through the day, check it each morning and evening, and ask your piercer about a shorter post — excess length lets the end move more than it should. Ends that will not stay tight at all usually mean worn threads, and the piece needs replacing.
What About Hinged and Seamless Rings?
Not all piercing jewelry uses this system. Hinged hoops (clickers) and seamless rings are single-piece designs:
Hinged hoops have a built-in hinge. Click open, slide through, click shut. Easy and secure. Popular for septum, daith, helix, conch and nose.
Seamless rings are continuous hoops you bend open to insert. Minimalist and clean, but awkward to open and close without ring-opening pliers.
Neither uses tops or threaded connections. If you want the least fiddly jewelry that exists, hinged hoops are hard to beat.
FAQ
Can I use a threadless top with an internally threaded post, or the reverse?
No. They are not cross-compatible. A threadless pin will not grip inside a threaded post, and a threaded pin will not tension in a threadless post. Match the system.
Are threadless ends really secure?
When the pin is bent correctly, yes. People wear them continuously — sleeping, exercising, showering — without problems. If an end feels loose, bend the pin a little more.
How do I tell what I already have?
Try pulling the end straight off. If it comes away with no twisting and you see a smooth, slightly bent pin, it is threadless. If you have to unscrew it, you will see tiny threads on the pin — internally threaded.
Which do professional piercers prefer?
Most modern piercers reach for threadless on initial piercings: it is easier to adjust as swelling goes down and easier for clients to manage at home. Plenty still use internally threaded for specific applications. Both meet the Association of Professional Piercers' standards for initial jewelry.
Can I mix brands with threadless?
Usually, as long as the gauge matches — most threadless follows the same standard. This is another edge over internally threaded, where thread pitch varies.
Is threadless good for initial piercings?
Yes. The smooth post is gentle on a fresh piercing, and the system makes it simple to swap to a shorter post once initial swelling subsides, without a return trip to the studio.
Is "push-pin" different from "threadless"?
No. Push-pin, push-fit and threadless all describe the same tension-held system.
The Bottom Line
Threadless is the modern standard and the easier system for most people. Internally threaded is the proven classic and still works well. Both are safe, both come in implant-grade titanium, and the real difference is convenience.
The decision that actually matters is not which of those two you pick — it is making sure you buy a matching post and top in the right gauge. That is the part people get wrong.
