Threadless vs Threaded Jewelry: What's the Difference and Which Is Better?
If you've ever shopped for piercing jewelry — especially flat back labrets, nose studs, or cartilage earrings — you've seen the terms "threadless," "internally threaded," and "externally threaded." They all look similar in photos, so what's the actual difference? And does it even matter?
Short answer: yes, it matters a lot. The threading system affects how easy your jewelry is to use, how comfortable it feels, and how safe it is for your piercing. Let's break it all down.
The Three Types of Threading in Body Jewelry
All body jewelry that has a removable end (like a flat back labret with a decorative top, or a barbell with screw-on balls) uses one of three connection systems:
1. Externally Threaded — The threads (grooves) are on the outside of the post/bar. The post screws directly into the decorative end. This is the oldest and cheapest style.
2. Internally Threaded — The threads are on the inside of the post/bar. The decorative end has a thin threaded pin that screws into the hollow post. This is the professional piercer standard.
3. Threadless (Push-Pin / Push-Fit) — No threads at all. The decorative top has a slightly bent pin that pops into the hollow post and is held in place by tension. This is the newest and increasingly most popular system.
Externally Threaded Jewelry: The Budget Option
Externally threaded jewelry is what you'll find at most mall kiosks, Amazon basics sellers, and budget 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 against the inside of your piercing channel every time you insert or remove the jewelry. For a healed piercing, this causes minor irritation. For a healing piercing, it can cause real damage — tearing delicate fistula tissue, introducing bacteria, and setting back your healing timeline.
This is why virtually every professional piercer refuses to use externally threaded jewelry. The Association of Professional Piercers (APP) specifically recommends against it for initial piercings.
When externally threaded is acceptable: Honestly? It's best avoided entirely. Even for healed piercings, internally threaded or threadless options are more comfortable and not significantly more expensive. The only reason externally threaded jewelry still exists is that it's cheaper to manufacture.
Internally Threaded Jewelry: The Professional Standard
Internally threaded jewelry has been the gold standard in professional piercing studios for years. The threads are hidden inside the hollow post, and the decorative end has a small threaded pin that screws into the post.
Why it's better than externally threaded: The outside of the post is completely smooth. When you insert it through your piercing, there are no threads to catch or scrape against tissue. This makes insertion much more comfortable and significantly safer for healing piercings.
The downsides: Internally threaded jewelry can be fiddly to work with. The threaded pins on the decorative ends are tiny — often less than 2mm — and screwing them in requires good dexterity and sometimes a pair of pliers or hemostats. If your hands are even slightly wet or oily, the tiny end can slip and you'll spend five frustrating minutes trying to screw on a ball that's smaller than a grain of rice.
Also, the threads can wear out over time with repeated screwing and unscrewing, eventually leading to ends that don't stay secure. Some people also find that internally threaded ends gradually loosen throughout the day, especially in piercings with a lot of movement.
We carry a range of internally threaded jewelry in implant-grade titanium for those who prefer this system.
Threadless (Push-Pin) Jewelry: The Modern Standard
Threadless jewelry — also called push-pin or push-fit — is the fastest-growing system in the piercing industry. Instead of threads, the decorative top has a thin pin (about 1cm long) that you bend slightly and then push into the hollow post. The tension of the bent pin inside the straight post holds everything together securely.
How it works:
1. Take the decorative top and gently bend the pin to about a 15-20 degree angle
2. Line up the pin with the opening in the post
3. Push it in — you'll feel a slight click or snap as the bent pin creates tension against the inside of the post
4. That's it. It's in. Secure and comfortable.
To remove it, you just pull the top straight out with a firm, steady tug. No twisting, no tools, no tiny screws to fumble with.
Our VitalFit™ Threadless System uses this exact mechanism with implant-grade titanium, available in 6 sizes to fit every piercing type.
Threadless vs Internally Threaded: Head-to-Head Comparison
Since externally threaded is best avoided, the real comparison is between threadless and internally threaded. Here's how they stack up:
Ease of use: Threadless wins by a mile. Push in, pull out — done. No tiny screws, no threading, no tools needed. Anyone can do it, even with wet hands or limited dexterity. Internally threaded requires patience and fine motor skills to screw in tiny ends.
Security: Both are secure when properly fitted. Internally threaded ends can gradually unscrew with movement (especially in lip or tongue piercings). Threadless ends stay put because the tension is constant — they don't gradually loosen. However, if the pin isn't bent enough, a threadless end can pop out unexpectedly.
Versatility: Threadless is more versatile. All threadless tops are compatible with all threadless posts of the same gauge. This means you can buy one bar and swap between dozens of different decorative tops. With internally threaded, the thread pattern must match exactly, and different brands sometimes use slightly different thread pitches.
Safety for piercings: Both are equally safe. Neither has exposed threads that can damage tissue. The smooth post slides through the piercing channel without catching or scraping.
Comfort: Nearly identical when wearing. The main comfort difference is during insertion and removal — threadless is faster and less fiddly, which means less time spent manipulating jewelry near a sensitive piercing.
Durability: Threadless has a slight edge. Internal threads can strip or wear out over time with repeated use. Threadless pins can be re-bent if they lose tension, effectively giving them unlimited lifespan.
Price: Very similar for the same quality level. Both systems are available in implant-grade titanium at comparable price points. Browse our threadless jewelry and internally threaded jewelry to compare.
Which System Should You Choose?
Choose threadless if:
You want the easiest jewelry to change on your own. You like switching up your look frequently (different tops for work vs. going out). You have multiple piercings and want one system that works for all of them. You have limited dexterity or find tiny screws frustrating. You're new to body jewelry and want the simplest option.
Choose internally threaded if:
You prefer the "locked in" feeling of a screwed connection. Your piercing is in a high-movement area (tongue, lip) and you want extra security. You already have internally threaded jewelry and want compatible pieces. Your piercer recommends it for your specific piercing type.
Our recommendation: For most people, threadless is the better choice. It's easier, more versatile, and just as safe. The piercing industry has been trending toward threadless for years, and it's becoming the new standard for good reason.
Understanding Gauge and Compatibility
Regardless of which threading system you choose, you need to match the gauge (thickness) of the top to the post:
Threadless: The top's pin gauge must match the post's inner diameter. Standard threadless pins come in 18G and 16G. A 16G threadless top will NOT fit in an 18G post — the pin is too thick.
Internally threaded: The threaded pin must match the thread pattern inside the post. Most quality body jewelry uses the standard thread pitch for each gauge, but cheap jewelry sometimes uses non-standard threads. Always buy from reputable sources to ensure compatibility.

How to Insert and Remove Each Type
Threadless (Push-Pin):
Insert: Bend the pin slightly (about 15-20 degrees). Hold the post/back steady against your skin. Push the top into the post until it clicks and feels snug. Give it a gentle tug to make sure it's secure.
Remove: Hold the post/back steady. Grip the decorative top firmly and pull straight out with a steady, even force. Don't twist — just pull.
Pro tip: If your threadless end feels loose, pull it out and bend the pin a little more. If it's too tight and hard to remove, straighten the pin slightly. You control the tension.
Internally Threaded:
Insert: Hold the post/back steady. Place the decorative end against the opening and turn clockwise. Keep turning until it's snug. Don't overtighten — you can strip the threads.
Remove: Hold the back steady. Turn the decorative end counter-clockwise until it releases. If it's stuck, try wearing latex gloves for better grip or use a pair of clean hemostats.
Pro tip: If your threaded end keeps unscrewing during the day, apply a tiny drop of Loctite 222 (the purple, lowest-strength version only) to the threads before screwing it on. This is what piercers use.
What About Hinged and Seamless Rings?
Not all piercing jewelry uses the threadless/threaded system. Hinged hoops (clickers) and seamless rings are single-piece designs:
Hinged hoops have a built-in hinge mechanism. You click them open, slide through your piercing, and click them shut. They're incredibly easy to use and very secure. Popular for septum, daith, helix, conch, and nose piercings.
Seamless rings are continuous hoops that you bend open slightly to insert. They're minimalist and clean-looking but can be tricky to open and close without ring-opening pliers.
Neither of these uses tops or threaded connections — they're standalone pieces. If you want the easiest possible jewelry experience, hinged hoops are hard to beat.
FAQ
Can I use a threadless top with an internally threaded post (or vice versa)?
No. These systems are not cross-compatible. A threadless pin won't grip inside a threaded post, and a threaded pin won't create tension in a threadless post. You need to match the system.
Are threadless ends really secure? Won't they fall out?
When properly fitted (pin bent to the right angle), threadless ends are extremely secure. Many people wear them 24/7 including during sleep, exercise, and showering without any issues. If an end feels loose, just bend the pin a bit more.
How do I know if my jewelry is threadless or internally threaded?
Pull the decorative end off (or try to). If it pulls straight out with no twisting, it's threadless — you'll see a smooth, slightly bent pin. If you need to unscrew it (twist counter-clockwise), it's internally threaded — you'll see tiny screw threads on the pin.
Which system do professional piercers prefer?
Most modern piercers use threadless for initial piercings because it's easier to adjust during swelling, easier for clients to maintain at home, and just as safe as internally threaded. However, many piercers still use internally threaded for certain applications. Both are APP-approved.
Can I mix and match brands with threadless jewelry?
Generally yes, as long as the gauge matches. Most threadless jewelry follows the same standard, so a top from one brand will usually fit a post from another. This is another advantage over internally threaded, where thread pitch can vary between brands.
Is threadless jewelry good for initial piercings?
Absolutely. Many piercers now prefer threadless for initial piercings because the smooth post is gentle on fresh piercings, and the system makes it easy to swap to a shorter post once initial swelling goes down — without needing to return to the piercer.
What's the difference between "push-pin" and "threadless"?
They're the same thing. "Push-pin," "threadless," and "push-fit" all refer to the same system — a smooth pin held in place by tension rather than threads.
The Bottom Line
If you're choosing between threadless and internally threaded, here's the simplest way to think about it: threadless is the modern standard that's easier for most people, while internally threaded is the proven classic that still works great.
Both are safe, both are professional-grade, and both are available in implant-grade titanium. The main difference is convenience — and threadless wins on that front for the majority of piercings and people.
