What Is Internal Threading in Piercing Jewelry?
Internal threading jewelry is designed with a smooth post, where the threaded part is inside the bar.
The decorative end screws into the post, meaning the surface that passes through your piercing stays polished and smooth.
This makes internally threaded jewelry one of the safest options for both new and healing piercings.
What Is External Threading in Piercing Jewelry?
External threading jewelry has threads on the outside of the post.
When inserting or removing it, those threads pass directly through your piercing.
This can create friction and increase the risk of irritation—especially in a fresh piercing.
Internal vs External Threading: What’s the Difference?
Understanding the difference between internal vs external threading helps you choose safer jewelry.
Comfort and Insertion Experience
- Internal threading: Smooth, less painful insertion
- External threading: Can feel rough or scratchy
Because internal threading piercing jewelry doesn’t drag threads through the skin, it offers a much more comfortable experience.
Safety for Healing Piercings
- Internal threading: Best for new piercings and healing stages
- External threading: Higher risk of irritation and tissue damage
Using externally threaded jewelry too early can slow healing and cause unnecessary trauma.
Irritation and Piercing Bumps
- Internal threading: Lower chance of irritation bumps
- External threading: More likely to cause redness and bumps
If your piercing keeps getting irritated, switching to internally threaded jewelry can help reduce problems.
Jewelry Quality and Standards
- Internal threading: Common in professional, high-quality jewelry
- External threading: Often found in lower-cost, mass-produced pieces
Many professional piercers prefer internal threading because it meets higher safety standards.
Which Is Better: Internal or External Threading?
For most situations, internal threading is better.
It is especially recommended for:
- New piercings
- Sensitive skin
- Piercings prone to irritation
If you’re serious about healing and comfort, internally threaded piercing jewelry is the safer choice.
Can You Use External Threading Safely?
External threading jewelry can be used if:
- Your piercing is fully healed
- The jewelry is high quality
- You insert it carefully
However, it’s still not ideal for long-term use compared to internal threading.
When Should You Switch to Internally Threaded Jewelry?
You should consider upgrading if:
- Your piercing hurts after changing jewelry
- You experience repeated irritation
- Your jewelry feels rough during insertion
Switching to internal threading piercing jewelry can significantly improve comfort and healing.
Best Jewelry Materials for Internal Threading
For the best results, combine internal threading with high-quality materials:
- Implant-grade titanium
- Surgical steel
- Hypoallergenic metals
This combination helps reduce irritation and supports faster healing.
