What is EN ISO 898-1:2013?

EN ISO 898-1:2013 is a technical standard that specifies the mechanical and physical properties of bolts, screws, and studs made of carbon steel and alloy steel. This standard covers fasteners with coarse pitch thread M1.6 to M39 and fine pitch thread M8x1 to M39x3.

Key Requirements of EN ISO 898-1:2013

The standard defines various requirements for bolts, screws, and studs, ensuring their quality and reliability. Here are some key requirements:

Tensile strength: The fasteners should be capable of withstanding a specific tensile load without breaking.

Proof load: It determines the maximum load that the fastener can bear without experiencing permanent deformation.

Hardness: The hardness of the fasteners should fall within a specified range to ensure proper functionality and resistance to deformation.

Thread tolerance: EN ISO 898-1:2013 sets specific thread tolerances to ensure compatibility and ease of assembly.

Testing and Certification Processes

To comply with EN ISO 898-1:2013, manufacturers are required to conduct a series of tests on their fasteners. These tests include:

Tensile test: Fasteners are subjected to tension until failure to determine their ultimate tensile strength.

Proof load test: Fasteners are tightened to a prescribed torque and then checked for any permanent deformation.

Hardness test: A hardness tester is used to measure the hardness of the fasteners.

Dimensional checks: The dimensions of the fasteners, including thread pitch and diameter, are carefully inspected.

Benefits and Importance of EN ISO 898-1:2013

The standard plays a crucial role in various industries, including automotive, construction, and machinery. Benefits of complying with EN ISO 898-1:2013 include:

High-quality fasteners: The standard ensures that fasteners meet stringent quality requirements, reducing the risk of failure and ensuring safety.

Interchangeability: With standardized thread tolerances, fasteners from different manufacturers can be easily interchanged.

Reliability: EN ISO 898-1:2013 ensures that fasteners can withstand specified loads without failing, providing confidence in their performance.

Compliance with regulations: Many industries require compliance with specific standards, and adherence to EN ISO 898-1:2013 helps meet those regulatory requirements.

In conclusion, EN ISO 898-1:2013 sets forth essential requirements for carbon steel and alloy steel bolts, screws, and studs. Compliance with this standard ensures the reliability, interchangeability, and overall quality of fasteners, leading to increased safety and customer satisfaction in various industries.
