When shopping for body piercing jewelry, especially on wholesale platforms, you’ll often see a specification that makes some buyers pause: “Externally Threaded.”
Many blogs claim that internally threaded jewelry is the only safe option. While internal threading is excellent for initial piercings, externally threaded tops (like our F136 Titanium Demon Balls & Spiky Cones) remain the backbone of the industry.
So, why are externally threaded accessories still flying off the shelves? Let’s break down the facts.

1. Cost-Effectiveness: Stock More for Less

For professional piercers and studio owners, inventory management is everything.
  • Lower Manufacturing Cost:​ Internal threading requires precision drilling inside the tiny post. External threading is simpler to machine, making it more affordable.
  • Higher Margin:​ For shop owners, this means you can stock a wider variety of shapes—from flat base studs​ to spiky cones—without breaking the bank. You get the same ASTM F136 Implant Grade Titanium​ benefits at a fraction of the cost.

2. Durability & Maintenance

Let’s be honest: threads wear out.
  • Stronger Posts:​ With external threading, the thread is part of the metal post. It is generally thicker and less prone to snapping than a hollow internally threaded post.
  • Easy Replacement:​ If the thread wears out over time, replacing an externally threaded top is cheap and easy. This is why they are called “Basic Accessories”​ or “Replacement Ends.”

3. Material Matters More Than the Thread Direction

Here is the most important secret in the industry: The material is more critical than the thread type.
Whether internal or external, if the jewelry is made of low-quality steel, it will cause irritation. Our F136 Titanium​ accessories solve this problem:
  • Implant Grade:​ We use ASTM F136 Titanium, which is biocompatible and safe for healing.
  • Hypoallergenic:​ Nickel-free and lead-free. Even with external threads, the risk of allergy is virtually zero because the titanium is inert.

4. Versatility: From Demon Balls to Spiky Cones

Certain designs are easier to produce with external threading.
  • Complex Shapes:​ Intricate designs like Demon Balls, Pyramid Studs, and Small Light Bulbs​ often feature external threads to maintain structural integrity.
  • Compatibility:​ Most standard labret posts and barbells in the market are designed to fit universal external thread sizes (e.g., M0.9, M1.2).

How to Use Externally Threaded Jewelry Safely

If you are a consumer worried about the “sharp” threads:
  1. Don’t slide it through the hole.​ Unscrew the top from the back, then insert the post, and finally screw the top back on from the front.
  2. Use it for healed piercings.​ External threads are best used as replacement tops​ for piercings that are already fully healed.

Conclusion: The Smart Choice for Healed Piercings

While we recommend internally threaded jewelry for fresh piercings, F136 Titanium Externally Threaded Tops​ are the smart choice for:
  • Healed piercings​ (Earlobes, Cartilage, Lips).
  • Studio consumables​ (Affordable replacements).
  • Trendy styles​ (Unique shapes like spikes and skulls).
