Threadless Jewellery, Made Simple
A gentle guide to threadless ends and compatible labret posts — including how the tension-fit system works, what to check before changing healed jewellery, and when to ask a professional piercer for fitting help.
What is threadless jewellery?
Threadless jewellery is also known as push-fit or press-fit jewellery. Instead of screwing together, the decorative end has a smooth pin that pushes into a hollow labret post.
The jewellery is held securely by gentle tension. A tiny bend in the pin helps the end grip inside the post, keeping the jewellery in place.
When adjusted correctly, the end should feel secure and sit flush against the post. It should never need to be forced.

How to Bend a Threadless Pin
Threadless jewellery stays secure through gentle tension. This illustration shows the correct way to create a small adjustment in the pin before testing the fit.
Before changing your jewellery
Only change jewellery yourself if the piercing is fully healed and comfortable. If your piercing is fresh, irritated, swollen, sore, tight, bleeding, or difficult to access, please book a professional fitting rather than forcing jewellery in yourself.
Common fit issues
Collapsible content
FAQ 1 — Can I bend a threadless pin myself?
Some threadless manufacturers use a controlled bend in the pin to create tension, but the correct method depends on the exact system. Follow the manufacturer’s instructions for your end and post rather than assuming one bend works for every brand. If you are unsure, a professional piercer can adjust it for you.
FAQ 2 — How much should I bend the pin?
There is no universal bend angle that should be applied to every threadless system. Some manufacturers publish their own fitting instructions for specific posts and ends. Follow the instructions for the exact jewellery you own, use the minimum adjustment required, and never force the end into the post.
FAQ 3 — Why does my threadless end keep falling out?
The pin may not have enough tension, the post may not be compatible, or the pin may not be fully inserted. Remove the jewellery safely and check the fit before wearing it again.
FAQ 4 — Why will my threadless end not go in?
The pin may be over-bent, misaligned, or the post may not be the correct size. Do not force it, especially while wearing it in the piercing.
FAQ 5 — What is an insertion taper or guide pin for?
Insertion tapers are professional instruments used by piercers to assist jewellery insertion when appropriate. They should not be used to force jewellery through a tight channel. Changes or downsizes needed while a piercing is healing should be performed by a qualified piercer.
FAQ 6 — Can I use threadless ends with any post?
Not always. Threadless ends and posts must be compatible, and fit can vary between manufacturers, gauges and component systems.
For piercing posts, use jewellery whose material and construction are appropriate for body piercing; for titanium used in initial or healing piercings, look for implant-certified material meeting recognised ASTM or ISO implant standards and reliable material documentation.
FAQ 7 — What about curved or circular barbells?
Threadless ends are most commonly used with straight threadless labret posts and straight barbells. Curved and circular jewellery can vary, so if you are unsure which fitting you need, please book a professional fitting or contact us before ordering.
Shop threadless jewellery with confidence
Choose a compatible decorative end and correctly fitted threadless post. Only make uncomplicated jewellery changes yourself once the piercing is fully healed and comfortable; never force jewellery through the channel, and book a professional fitting whenever the size, compatibility or insertion is uncertain.
