What is EN ISO 898-2:2018?

EN ISO 898-2:2018 is a technical standard that provides detailed specifications for the mechanical properties of fasteners made from carbon steel or alloy steel, with thread sizes from M1.6 to M39. This standard specifies requirements for nuts, bolts, screws, and studs, including their dimensions and materials, as well as their mechanical properties such as tensile strength, proof load, hardness, and torque capabilities. In this article, we will delve into the key aspects of EN ISO 898-2:2018, exploring its scope, applications, and importance in various industries.

The Scope of EN ISO 898-2:2018

EN ISO 898-2:2018 is part of a series of standards developed by the International Organization for Standardization (ISO) in collaboration with the European Committee for Standardization (CEN). It specifically focuses on the mechanical properties of externally threaded fasteners made from carbon steel or alloy steel, which are commonly used in construction, automotive, and machinery industries.

The standard covers the complete range of sizes for fasteners with metric coarse pitch threads, ranging from M1.6 to M39. It outlines specific requirements for different property classes, ensuring that fasteners meet certain performance standards based on their designated class.

Key Specifications and Requirements

EN ISO 898-2:2018 sets forth essential specifications and requirements for fasteners, including their thread designs, dimensions, and material compositions. Additionally, it defines various mechanical properties that these fasteners must possess in order to ensure their reliability and performance under different conditions.

Some of the key specifications outlined in this standard include the designation system for fasteners, which classifies them based on their property classes. These property classes are determined by various factors including the material type, heat treatment, and mechanical properties of the fastener.

Furthermore, the standard specifies testing procedures for evaluating critical mechanical properties of fasteners such as tensile strength, proof load, and hardness. These tests help determine the maximum load a fastener can withstand before failure, its capability to resist deformation, as well as its overall hardness and durability.

Importance and Applications

EN ISO 898-2:2018 is of great importance in ensuring the quality, reliability, and safety of fasteners used in a wide range of industries. By adhering to the specifications and requirements set forth in this standard, manufacturers can produce fasteners that meet the necessary performance standards, reducing the risk of product failure or accidents caused by faulty fasteners.

Fasteners compliant with EN ISO 898-2:2018 are extensively used in various applications, including construction, automotive manufacturing, aerospace, and heavy machinery industries. From securing structural components in buildings and bridges to assembling engines and machinery, these standardized fasteners play a crucial role in maintaining structural integrity and safety.

In conclusion, EN ISO 898-2:2018 provides comprehensive guidelines for the manufacture and use of fasteners made from carbon steel or alloy steel. By setting specific specifications and requirements, it ensures the quality and reliability of these fasteners, promoting safety and performance across different industries.
