Technical FAQs — Grade 8 Nut MTC Certificate
What heat treatment methodology is tracked on this certificate?
The MTC specifically logs a hardening cycle at 880°C and a tempering cycle at 550°C. These thermal processes are critical for achieving the required hardness and proof load strength for Property Class 8 nuts.
What specific mechanical tests are logged on the certificate?
For Grade 8 nuts, the certificate highlights Proof Load testing (kN) and Hardness testing (HRC). These ensure the nut will not strip or deform under the rated tensile load of its corresponding bolt.
Are dimensional and visual inspections included?
Yes, the certificate confirms 100% visual inspection found free from defects and dimensional conformance according to DIN 934 for Hexagon Nuts.
