Because there are many types of products, expert customers can understand them at a glance, but some casual customers do not understand them very well. I would like to explain here.:
For example, 4 points x 19mm
A score of 4 indicates the size of the thread opening, 19mm indicates that the outer diameter of the pagoda head is 19 mm, and so on. If you don't understand, please consult customer service. The quality is guaranteed, so you can take photos with confidence.
