GB\/T 6172.2-2016 Hex Thin Lock Nuts Non-Metallic Insert 1. Introduction Hexagon thin lock nuts with non-metallic inserts are essential fasteners in mechanical engineering, providing reliable locking mechanisms to prevent loosening under vibration. The GB\/T 6172.2-2016 standard specifies the dimensions, technical requirements, and markings for prevailing torque type hexagon thin nuts with non-metallic inserts.
