The bottom end is equipped with a horn shaped pressure ring, and the outer diameter of the pressure ring gradually increases along the direction away from the nylon nail head. There is also a buffer pad on the bottom surface, which can protect the surface of the object. A limited flow ring may be installed on the side wall of the nail head, while multiple anti loosening grooves are spaced on the side wall of the nail rod. The top of the nylon nail cap may sometimes have a contact ring for easy removal. 
-Specification and size: The common diameter is generally between 2.8-4.2 millimeters, and the length is in the range of 40-80 millimeters, but it can also be customized according to actual needs.
