①,Type V:
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.
Type M:
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. This type dose not have full loadability.
②,Material:
Steel, Strength class (material): 5,8,10,12(≤M16)。Standard DIN 267-4
