GSO ISO 898-7:2014 Scope

This part of ISO 898 specifies a torsional test for the determination of the breaking torque of bolts and screws with nominal diameters 1 mm to 10 mm with property classes 8.8 to 12.9 in accordance with ISO 898-1. The test applies to bolts and screws with thread less than M3 for which no breaking and proof loads are indicated in ISO 898-1, as well as to shot-t bolts and screws with nominal diameters 3 mm to10 mm which cannot be subjected to a tensile test. The minimum breaking torques are not valid for hexagon socket set screws.
