What is BS EN ISO 898-2:2012

BS EN ISO 898-2:2012 is a professional technical standard that provides guidelines for the mechanical properties and performance requirements of carbon steel and alloy steel fasteners. This standard specifies the mechanical and physical properties, including tensile strength, yield strength, elongation, and hardness, for threaded fasteners such as bolts, screws, and studs.

Scope and Application

The scope of BS EN ISO 898-2:2012 covers fasteners made of carbon steel or alloy steel with thread sizes from M1.6 to M39 and length up to 1000mm. It applies to both coarse and fine pitches and includes fasteners with different property classes, such as 4.6, 5.8, 8.8, 10.9, and 12.9. This standard is widely used in various industries, including automotive, construction, and manufacturing.

Testing and Compliance

BS EN ISO 898-2:2012 requires fasteners to undergo specific tests to ensure they meet the specified mechanical and physical properties. These tests include tensile testing, which measures the maximum force a fastener can withstand without breaking, and hardness testing, which determines the resistance of the material to indentation or penetration.

In addition to testing, this standard establishes acceptance criteria for dimensions, surface finish, and marking. Fasteners that comply with BS EN ISO 898-2:2012 are labeled accordingly, allowing users to identify their grade and performance characteristics.

Benefits and Importance

Adhering to BS EN ISO 898-2:2012 ensures that fasteners used in various applications have the required strength, reliability, and durability. By following this standard, manufacturers can produce high-quality fasteners that meet international specifications, leading to safer and more efficient products.

For end-users, the use of BS EN ISO 898-2:2012 compliant fasteners provides confidence in the integrity of assembled parts, reducing the risk of failures, accidents, or costly repairs. It also facilitates global trade, as this standard is recognized and accepted by many countries worldwide.
