Which bolts exist for a sex doll head?
For a sex doll head, there are three different connections or bolts, namely:
- Threaded bolt
- Snap-on or click-on bolt
- Pivot snap-on or Sway click-on bolt
The snap-on and pivot snap-on bolts are very similar; however, the pivot snap-on also allows the head to tilt sideways and move up and down through a ball joint. This provides the most freedom of movement.
The threaded bolt is cheaper than the other two options and is therefore the most chosen for budget sex dolls. Often, you can ask the supplier which of the three bolts is used and upgrade if desired.
Both full-size sex dolls and torso sex dolls with heads benefit from the right connection.
Almost all sex dolls with heads have an M16 neck connection; some have an M8 connection.
Why is a good bolt or connection so important?
A good bolt that offers freedom of movement provides a different appearance and more flexibility for the sex doll. Turning and tilting the face creates a more feminine and gentle expression.
The photo below shows how a woman’s expression changes when she tilts and turns her head slightly. The right bolt also makes this sweet expression possible for sex dolls.
Now that we know which bolts exist and why they are important, we will further discuss the three types below.
Threaded bolt connection
A threaded bolt connection is a simple connection with full threading. This option is often used as the most budget-friendly choice; you simply screw the bolt into the neck and then rotate the head on the doll until it is firmly in position.
Pros and cons of the threaded bolt
Advantages of the threaded bolt:
- Cost-saving, the cheapest option of the three
Disadvantages of the threaded bolt:
- Often does not allow the face to look 100% straight ahead after securing
- Offers no flexibility or rotational ability once secured
Snap-on connection
A snap-on connection is a bolt equipped with small balls and 50% threading that fit into the thread of the head. With this bolt, you simply click the head securely into the neck with one action, allowing the head to turn left and right.
Pros and cons of the snap-on bolt
Advantages of the snap-on bolt:
- Faster to secure and release
- Keeps the doll looking straight ahead after securing
- Allows the head to look left and right after securing
Disadvantages of the snap-on bolt:
- Slightly more expensive
- May come loose slightly faster than the threaded bolt during very rough movements
Pivot snap-on connection
With this bolt, you simply click the head onto the body with one action, and thanks to the ball joint in the middle of the bolt, you can rotate and tilt the head in all directions.
A pivot snap-on connection, also known as a sway click-on connection, is almost the same as a normal snap-on connection. The pivot function includes a ball joint so you can also tilt the head and make it look up and down.
Pivot, sway, tilt, turn, or other synonyms are often used in combination with click-on, snap-on, or adapter. They all broadly refer to the same part with the same function.
Pros and cons of the pivot snap-on bolt
Advantages of the pivot snap-on bolt:
- Faster to secure and release
- Always keeps the doll looking straight ahead after securing
-
Offers the ability to look up, down, left, and right after securing looking, with permanent 360 flexibility and tilt function
Disadvantages of the pivot snap-on bolt:
- Most expensive option
- May come loose slightly faster than the threaded bolt during very rough movements
Conclusion
If you want the most realistic bolt, choose a pivot snap-on connection, a bolt that can rotate and is equipped with a ball joint. This allows you to turn the sex doll's head up, down, left, and right, and tilt the head for full flexibility and a nicer appearance.
The only disadvantage of this connection is that it comes loose more easily during rough movements than a threaded bolt, but it stays in place with normal use.
If you choose the cheapest option, you go for a threaded bolt connection, which unfortunately offers no freedom of movement, meaning the sex doll's head always remains fixed in the same position. The advantage is that this threaded bolt connection is the strongest of all. However, with normal use, the extreme strength of the threaded bolt is unnecessary.
