Design and selection

Class 8 refers to the nut's mechanical properties. DIN 985, ISO 10511 and PN 82175 designations are catalogue references for this family; if a specific standard is required, check the requirements of the joint. Product grade A follows from the dimensional table for size M8.

Before installation, check the diameter and pitch of the mating thread and joint requirements. Do not apply data for fine thread M8×1 to this M8×1,25 variant. Select tightening torque for the entire joint and its operating conditions.
