EN 10061:2003

Overview

EN 10061:2003 is a European Standard developed by CEN that defines the nominal dimensions and tolerances on shape and dimensions for hot rolled hexagon steel bars intended for general purposes. This standard ensures uniformity and quality control in the production and use of hexagonal steel bars across industries. It specifies the exact size characteristics and acceptable deviations to guarantee compatibility, performance, and safety in structural and mechanical applications.

Key Topics

• Dimensions Specification
  The standard provides detailed nominal sizes for hot rolled hexagon steel bars, specifying widths across flats and lengths suitable for various manufacturing and construction needs.

• Tolerances on Shape
  EN 10061:2003 outlines permissible variations in the geometric shape of the hexagon steel bars, ensuring that they remain within specific limits to maintain proper fit and function in assemblies.

• Dimensional Tolerances
  It defines the allowable deviations from the nominal dimensions to accommodate manufacturing variations while ensuring that the final product meets quality requirements.

• General Purpose Usage
  The specification is designed for hexagon steel bars used in a broad range of applications without special requirements for enhanced mechanical properties or surface finishes.

Applications

• Mechanical Engineering
  Widely used for shafts, fasteners, spacers, and pins where consistent hexagonal shape and dimensions are crucial for assembly and performance.

• Construction and Infrastructure
  Utilized in structural components, frameworks, and reinforcement where hot rolled steel bars provide durability and strength.

• Tooling and Machinery
  Suitable for parts that require machining or shaping after rolling, benefitting from standard sizes and tolerances to simplify design and production.

• General Manufacturing
  Used in fabrication of parts where hexagonal cross-sections provide functional advantages such as improved grip or mechanical engagement.
