1. High connection strength
The countersunk drill tail nail can firmly fix the connecting parts together through the countersunk design of the head and the thread at the tail, with high connection strength. At the same time, the threaded part of the countersunk drill tail nail can be subjected to different degrees of heat treatment as needed to improve its tensile and shear strength.
2. Good self-locking performance
During the connection process of the countersunk drill tail nail, the countersunk design of the head can automatically lock the thread, forming a self-locking structure. This self-locking performance can effectively prevent thread loosening and ensure the reliability of the connection.
3. Easy to install
The tail design of the countersunk drill tail nail can be adjusted according to the shape and size of the connected parts, making it easy to pass through the parts and connect them. At the same time, the head countersunk design of the countersunk drill tail nail can also reduce friction with the connected parts, making installation smoother.
