Hexagon screw according to DIN EN ISO 4017, including galvanized flange nut. The strength class of the screw is stamped on the screw head. Especially for connections that have to transfer vertical loads via friction, it is essential to pay attention to the screw tightening torque and to check it with the torque wrench! In product combinations (hexagon screw with flange nut), the lower strength class should be used to determine the torque. Dimensions (approx. dimensions) Thread: M 10 Screw length: 40 mm Strength class screw: 70 Strength class nut: 80 Max. screw tightening torque: 32 Nm Material: stainless steel, material no. 1.4404, AISI 316L
