Open end blind rivets with break pull mandrel and countersunk head - A2/A2

This standard establishes specific requirements for flat-headed pop rivets designed with a single-sided access capability. It covers rivets featuring a perforated head and a breakstem core, designated under material grades suitable for general industrial applications. The document defines precise dimensional tolerances, mechanical properties, and performance criteria necessary to ensure the reliability and interchangeability of these fastening elements. It outlines the methods for testing head diameter, shank length, grip range, and shear strength to verify compliance with the established specifications. Furthermore, it addresses the structural integrity of the breakstem mechanism, ensuring consistent fracture behavior during installation. The content serves as a technical reference for manufacturers and users involved in the production and selection of such rivets within engineering and manufacturing sectors. By adhering to these guidelines, stakeholders can achieve uniform quality in assembly processes across various industries. The standard provides a framework for evaluating the suitability of these fasteners in diverse environmental conditions without compromising structural safety or performance efficiency.
