DIN 980 Locking principle a. The locking principle of 980-v type nut is as follows: through die stamping, the screw thread of the nut itself has about 3 teeth deformed, and after deformation, the inner diameter of the nut thread is slightly smaller than the outer diameter of the bolt thread.

Made to DIN 980M standard (ISO 7042), the Metal insert is more durable than plastic or nylon inserts making it beneficial for use with products that are serviceable or require maintenance. The Metal Insert Self Locking Nut can also be used to assist in sealing the bolt thread against seepage of oil, water, petrol, paraffin, and other liquids.

DIN980根据其锁紧形式主要有 DIN980V型 和 DIN980M型。 V型与M型的区别： 980 V型靠螺母自身的螺纹变形位置起到锁紧防松功能，常见的形式有：端面三点式、椭圆式、侧面挤压式。 980 M型螺母内嵌金属锁紧片，靠锁紧圈起到防松作用。 本页所介绍的产品为DIN980M。 980 M型螺母的锁紧原理为：螺母内嵌经过热处理的金属片，该金属片内径略小于螺栓螺纹外径，螺母拧紧后，金属片卡住螺栓螺纹，可以有效的起到防松、抗震的作用。 锁紧螺母安装时必须借助工具 …

Single-piece metal nuts are nuts without an insert, in which increased friction is created by the appropriate deformation of the prevailing torque element of the nut. Two-piece metal nuts are nuts, in which increased friction is created by an additional metal element inserted in the prevailing torque element of the nut.
