EN 10269 Bolting Specification

Scope

EN 10269 Specification – High-Performance Fastener Materials

Adfast Component LTD offers premium-quality semi-finished products, bars, and rods conforming to the EN 10269 specification. This European Standard ensures the highest performance for fasteners used in elevated or low temperatures, made from non-alloy, alloy (including stainless) steels, and nickel alloys. Our materials comply with EN 10021 general technical delivery conditions, guaranteeing reliability and durability.

Once published in the EU Official Journal under Directive 97/23/EC, EN 10269 materials are presumed to meet Essential Safety Requirements (ESRs) concerning technical data. However, assessing their suitability for specific equipment remains essential. Choose Adfast Component LTD for certified fastener materials that meet industry standards.

  • a Elements not listed in this table may not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast. All appropriate precautions are to be taken to avoid the addition of such elements from scrap and other materials used in production which would impair mechanical properties and the usefulness of the steel.
  • b A controlled sulphur content of 0,015 % to 0,030 % improves the machinability and is therefore recommended and may be agreed at time of enquiry and order. For weldability, a controlled sulphur content of 0,008 % to 0,030 % is recommended and may be agreed at time of enquiry and order.
