The thread specifications of type 2 nuts range from M5 to M36. The performance grades are 9 and 12, and the product grades are A and B. Grade A is used for specifications of 16mm or less; Grade B is used for specifications larger than 16mm! (Here, A and B refer to the precision grades)
Due to the high performance requirements of type 2, the thickness of the nuts is relatively thick.
The performance grades of bolts and nuts refer to the mechanical properties of the materials used (tensile strength and yield strength); the product grades are similar to the precision grades, with Grade A being the most precise and Grade C being the least precise.
