What types of bolts are available for a sex doll head?
There are three different connections or bolts for a sex doll head, 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, but the pivot snap-on also allows the head to tilt to the side and move up and down thanks to a ball joint. This offers the greatest freedom of movement.
The threaded bolt is cheaper than the other two options and is therefore the most popular choice for budget sex dolls. You can often 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 gives the sex doll a different look and greater flexibility. Turning and tilting the face creates a more feminine and sweeter appearance.
The photo below shows how a woman changes her appearance when she tilts and turns her head slightly. The right bolt also makes this sweet expression possible for sex dolls.
Now that we know what types of bolts there are and why they are important, we will 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 turn the head onto the doll until it is firmly in position.
Advantages and disadvantages of the threaded bolt
Advantages of the threaded bolt:
- Cost-effective, the cheapest of the three options
Disadvantages of the threaded bolt:
- Often does not let the face look 100% straight ahead once tightened
- Offers no flexibility or ability to turn once tightened
Snap-on connection
A snap-on connection is a bolt with small ball bearings and 50% threading that fit into the threads in the head. With this bolt, you simply click the head into the neck in one motion with one hand, and you can turn the head to the left and right.
Advantages and disadvantages of the snap-on bolt
Advantages of the snap-on bolt:
- Faster to secure and remove
- Keeps the doll looking straight ahead after securing
- Once secured, it lets the head look left and right
Disadvantages of the snap-on bolt:
- A little more expensive
- Can come loose a little more easily during very vigorous movements than the threaded bolt
Pivot snap-on connection
With this bolt, you simply snap the head onto the body in one motion, and the ball joint in the center of the bolt lets you turn and tilt the head in any direction.
A pivot snap-on connection, also known as a sway click-on connection, is almost the same as a standard 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, and other synonyms are often used with click-on, snap-on, or adapter. These terms broadly refer to the same part with the same function.
Advantages and disadvantages of the pivot snap-on bolt
Advantages of the pivot snap-on bolt:
- Faster to secure and remove
- Keeps the doll looking straight ahead after securing
-
Once secured, it lets the head look up, down, left, and right, with continuous 360-degree flexibility and a tilting function
Disadvantages of the pivot snap-on bolt:
- Most expensive option
- Can come loose a little more easily during very vigorous movements than the threaded bolt
Conclusion
If you want the most realistic bolt, choose a pivot snap-on connection: a rotatable bolt with a ball joint. This lets you turn the head of a sex doll up, down, left, and right, and tilt it for full flexibility and a more attractive appearance.
The only downside of this connection is that it can come loose more easily than a threaded bolt during vigorous movements. It stays in place during normal use.
If you go for the cheapest option, choose a threaded bolt connection. Unfortunately, this offers no freedom of movement, so the head of the sex doll always stays fixed in the same position. The advantage is that this threaded bolt connection is the sturdiest of all. However, the extreme sturdiness of the threaded bolt is unnecessary under normal use.
