The M16 Thread Connector
The M16 model is one of the most common doll head connectors in the market today, used by many well-known brands as their standard threaded connection. Its design ensures both connection stability and relatively easy head replacement.

Which mainstream brands use M16 thread-compatible doll heads?
WM Doll, IRONTECH Doll, Real Lady Doll, YL Doll, SE Doll, 6YE Doll, Funwest, Galatea doll, Elsababe Doll, Bezlya Doll, ZELEX Doll, Climax Doll, and others.
If your doll is from one of these brands, it uses the M16 standard thread connector. While different brands may have slight variations in specific designs, they are generally interchangeable. This means as long as the skin tone and style match, you can swap heads between these brands.

What types of doll heads are compatible with M16 threads?
There are many types of doll heads compatible with M16 threads, covering various styles and ethnicities, such as ROS sex doll heads, European, Asian, Latina, and Black skin tone styles, as well as ELF, Alien, and anime character heads. Whatever style you prefer, you're sure to find one that suits you!

What are the main types of M16 thread connectors?
M16 thread adapters come in different structural designs, each with varying levels of installation difficulty, stability, and range of motion.
1.Double-threaded screw
This connector design has threads on both sides, requiring rotation of both the head and neck for complete installation or removal. While installation is a bit tricky, once tightened, the doll head is very secure. You can confidently pose the doll's head without worrying about it falling off.

2.Single-threaded screw
Compared to double-threaded screws, this type of connector is easier to install and remove. You only need to rotate one side, while the other side can be directly aligned and pressed into place. The only drawback is that this connection method is slightly less secure, particularly when the doll is lying down, where the head might occasionally come loose.

3.Direct insert
The biggest advantage of this connector is its super simple installation. Both sides just need to be aligned and pressed together to complete the connection. While convenient, note that this connection method may not be as stable as threaded connections.

4.New upgraded rotatable connector
This new M16 connector features a ball-joint mechanism that improves the doll's range of motion and overall structure, allowing for more poses, including looking up, making movements more realistic and natural. In contrast, the standard adapter only allows the doll to tilt left and right or look down, limiting the range of motion and possible poses. Currently, SE Doll, IRONTECH Doll, and Real Lady Doll brands use this rotatable connector.


Comparison of M16 connector types and characteristics:
Type | Stability | Convenience | Suitable for |
---|---|---|---|
Double-threaded screw | ⭐⭐⭐⭐⭐ | ⭐⭐ | Users prioritizing stability, infrequent head changes |
Single-threaded screw | ⭐⭐⭐ | ⭐⭐⭐ | Frequent head changes, convenience priority |
Direct insert | ⭐⭐ | ⭐⭐⭐⭐⭐ | Ultimate convenience, quick assembly |
Rotatable connector | ⭐⭐⭐⭐ | ⭐⭐⭐ | Need for greater range of motion |

What if your doll doesn't have an M16 thread - how can you make it compatible?
If your doll doesn't have an M16 thread connector, don't worry - it's actually quite simple. You just need to purchase a dedicated adapter screw, which will allow non-M16 dolls to use M16 heads. The adapter screws shown in the image work well and aren't complicated to install. This way you can easily use your preferred doll heads!

Other Types of Connectors
While M16 is currently the most common connection method, some doll brands use different connector specifications. For example, WM Doll's anime series uses a rod-type connection rather than the traditional M16 thread. So be sure to check your doll's connector type before purchasing, or the head you buy might not fit at all!
How to Properly Install Doll Heads and Avoid Problems?
To ensure a secure connection while protecting the doll's connector, keep these points in mind during installation:
1. Confirm Connector Compatibility
If your doll has an M16 connector, use an M16 connector.
2. Don't Over-tighten
During installation, be careful not to overtighten the screws. Excessive tightening can damage the threads or the connection point between the head and body, potentially making it impossible to remove.
Tip: When the screw is too loose to maintain poses, the video below can help.
3. Align Properly
When installing, make sure to align the connectors correctly, or the catches might deform, affecting the lifespan of the connection.
4. Maintain Properly
If the connector becomes stuck or won't turn, apply a small amount of lubricant to keep it smooth.
5. Check the Connector
Regularly check if the connector is loose, and if it is, promptly readjust or tighten the screws to prevent the head from falling off.
6. Avoid Sudden Movements
Although connectors are generally very sturdy, try to avoid sudden movements when handling the doll to prevent connector damage.
