Overview
EN 3011:1998 (published by CEN) is an aerospace standard that specifies the characteristics of hexagon‑head bolts with relieved shank and long thread, manufactured in the heat‑resisting nickel‑base alloy NI‑P101HT (Waspaloy) and silver plated. The document defines the classification and performance level: 1 210 MPa (at ambient temperature) / 730 °C, and is intended for high‑temperature aerospace applications where corrosion resistance and elevated‑temperature strength are required.
Key topics
The standard focuses on the essential characteristics and performance requirements for this specific fastener type. Key technical topics include:
- Material specification: use of the nickel‑base alloy NI‑P101HT (Waspaloy) for heat resistance.
- Mechanical classification: designation 1 210 MPa (ambient) / 730 °C, indicating the required strength/temperature classification for the fastener in service.
- Geometry and form: hexagon head, relieved (reduced) shank, and long thread configuration for aerospace assemblies.
- Surface finish: silver plating to provide electrical conductivity and corrosion protection where specified.
- Intended aerospace use: requirements tailored to aircraft/space components exposed to elevated temperatures. Note: EN 3011 defines characteristics and classification; consult the full standard text for dimensional, marking and inspection details.
Applications
EN 3011:1998 is applicable where high‑temperature, corrosion‑resistant bolting is required in aerospace components, for example:
- Engine and hot‑section assemblies where fasteners must retain strength at elevated temperatures.
- Structural joints requiring a relieved shank and long thread for controlled clamping and assembly flexibility.
- Environments needing silver‑plated fasteners for conductivity or specific corrosion performance.
Who uses this standard:
- Aerospace fastener manufacturers and metallurgists producing NI‑P101HT (Waspaloy) bolts.
- Design and stress engineers specifying high‑temperature fasteners.
- Procurement and quality assurance teams verifying compliance with CEN aerospace requirements.
- Maintenance and overhaul organizations ensuring correct replacement parts.
Related standards
EN 3011 complements other aerospace fastener standards produced by CEN and national bodies that cover dimensional standards, testing procedures, marking, and alternate material classes. When specifying or procuring fasteners, review EN 3011 alongside applicable EN or ISO standards for threads, tolerances, and inspection to ensure full compliance.
