Technical FAQs — ISO 898-2 Class 8 MTC
What does property "Class 8" mean for a nut under ISO 898-2?
In the metric nut property class system, the number "8" designates that the nut can successfully withstand the proof load stress associated with matching bolts of property class 8.8 without stripping or thread failure. It guarantees a minimum proof load stress of 800 MPa.
What heat treatment is typical for Class 8 nuts?
Class 8 nuts are manufactured from carbon or alloy steel and are typically quenched and tempered to ensure they meet the rigorous hardness and proof load requirements specified in ISO 898-2, ensuring robust resistance under high mechanical stress.
Which bolts are compatible with ISO 898-2 Class 8 nuts?
Class 8 nuts are designed to mate perfectly with bolts of property class 8.8. Using matching fastener classes ensures joint reliability, predictable tensioning, and balanced structural integrity across industrial assemblies.
