Taking M12.5 × 1.25 65-10.9 bolt as an example, this paper studies the extreme distribution of minimum value tensile strength in order to evaluate reliability and stability product quality verify production process. Through data collection, parameter estimation, test prediction, it is concluded that: 1) conforms Gumbel distribution; 2) when return period 10000, predicted 1071.7 MPa ± 3.2 MPa, k...
