Hexagon Nuts DIN 934Metric Series – Dimensions, Physical Properties

Notes:

The nuts will generally conform to ISO 4032, DIN 934.1. Thread will conform to Class 6H of Din 13 Part 12 for Coarse Series –M-2. Material & Heat Treatment: To achieve mechanical properties of Class 8 or 10.3. Nuts of Property Class 8 are used with bolts of Property class 8.84. Nuts of Property Class 10 are used with bolts of Property class 10.9.5. (In general, nuts of a higher property class can replace nuts of a lower property class in a joint).6. In Bolts/Nuts assembly, tightening should be done by rotation of nuts. Torque Value as recommended in tables of bolts.7. Size in brackets is non preferred standards.8. All dimensions are in millimeters.9.
