Standard EN 28839: Mechanical Characteristics of Non-Ferrous Metal Fasteners

Technical Regulation EN 28839: Scope and Specifics

The international standard EN 28839 establishes strict requirements for the mechanical characteristics of metric fasteners made from non-ferrous alloys. The standard applies to bolts, screws, studs, and nuts with a nominal thread diameter from M 1.6 to M 39, manufactured in accordance with the ISO 261 metric system. The primary structural materials are copper, aluminum, and their derivative alloys. Experts at EV Group China emphasize that this standard is a direct equivalent to the international protocol ISO 8839.

It is important to note that the EN 28839 specification does not cover corrosion protection or the specific electrical conductivity parameters of the products. Designers should pay attention to the suitability of the alloys for target operational loads.
