Technical requirements and scope of the EN 10061 standard
This European standard EN 10061 establishes strict requirements for nominal dimensional characteristics, as well as limit deviations in shape and geometric parameters for hot-rolled steel hexagonal bars. This specification serves as a baseline for metallurgical enterprises and engineering departments, ensuring the standardization of products supplied by EV Group China.
The technological tolerances outlined in the standard guarantee high geometric precision when using hexagonal rolled products in mechanical engineering, steel structure construction, and the production of fasteners. EV Group China products strictly comply with the specified size ranges presented in Table 1. Applying this standard allows engineers to accurately calculate fit dimensions and minimize allowances for subsequent mechanical processing.
| Nominal size (mm) | Limit deviations (mm) |
|---|---|
| 10 – 20 | ±0.3 |
| 21 – 35 | ±0.4 |
| 36 – 50 | ±0.5 |
To select the optimal assortment of hot-rolled hexagon bars that meet the requirements of EN 10061, EV Group China specialists recommend relying on the preferred sizes indicated in industry specifications. The use of standardized rolled products is a guarantee of the reliability and durability of final assemblies and components.
