We certify that the fastener was manufactured sampled, tested and inspected in accordance with the specification and the results have been determined to meet the requirements of the specification.
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.
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.
Yes, the certificate confirms 100% visual inspection found free from defects and dimensional conformance according to DIN 934 for Hexagon Nuts.
