According to the thread length, it is divided into two types: full thread and non-full thread. The English name of the riding bolt is U-bolt. It is a non-standard part. The shape is U-shaped, so it is also called U-bolt. Both ends have threads that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as car plates. The spring is called a riding bolt because it fixes the object in the same way as a person riding on a horse.
