Allen Key Screw

Jinghong manufacturer uses high-speed grinding tools to punch the wire into bolt heads and rod bodies in one go, and the head rolling design enhances manual installation friction. The overall shape of the head is cylindrical, which ensures that the bolt head is uniformly stressed when in contact with the connected part, reduces local stress concentration, and improves the stability of the connection. The outer diameter of the cylindrical head is usually larger than the diameter of the screw, providing sufficient load-bearing area for the connection and ensuring stable performance when subjected to large loads.

Product Feature

The screw usually has metric or imperial threads, and the thread profile, pitch, and other parameters of the threads can meet the corresponding national standards, ensuring the interchangeability and universality of the bolt with the nut or other internal threaded parts. The half tooth bolt rod is located between the bolt head and the fully threaded section, and its diameter is usually slightly smaller than the larger diameter of the thread. This half tooth structure not only ensures the strength of the bolt connection, but also has certain advantages.
