The standardization and certification system of bolts and nuts is to ensure the quality and safety of products in order to achieve the interchangeability and universality of products between different industries and countries. Standardization system: The standardization of bolts and nuts is mainly developed and managed by the International Standards Organization (ISO) and national standardization bodies. ISO has developed many standards for bolts and nuts, such as ISO 4014:2011 (hex head bolts), ISO 4032:1999 (hex thin nuts) and so on. These standards specify the size, mechanical properties, material requirements, surface treatment and other requirements of bolts and nuts to ensure that bolts and nuts produced by different manufacturers have the same characteristics and interchangeability. Certification system: In order to ensure that bolts and nuts meet the requirements of the standard, it is usually necessary to verify through a certification system. Common certification systems are ISO 9001 quality management system certification, ISO/IEC 17025 testing and calibration laboratory certification. ISO 9001 certification ensures that the company has a sound quality management system and is able to provide products and services that meet the requirements. ISO/IEC 17025 certification ensures that laboratories have reliable and accurate testing capabilities for the mechanical properties and materials of bolts and nuts. The introduction of standardization and certification systems enables companies to follow a uniform set of codes and standards when producing bolts and nuts, ensuring product quality and safety. At the same time, through the certification can increase the competitiveness of enterprises and credibility, improve the market competitiveness of products. Copy content
