General Information
Overview - EN 3009:1998 (Aerospace bolts, Inconel 718, silver plated)
EN 3009:1998 is a CEN aerospace series standard that specifies the characteristics of hexagon head bolts with a relieved shank and long thread manufactured from the heat‑resisting nickel‑base alloy NI‑P100HT (Inconel 718) and finished silver plated. The standard defines the bolt classification as 1 275 MPa (at ambient temperature) / 650 °C, indicating suitability for high‑strength, elevated‑temperature aerospace applications.
Key topics and requirements
- Material specification: Bolts are made from NI‑P100HT (Inconel 718), a heat‑resisting nickel‑base alloy suited for elevated temperatures.
- Geometry and form: Hexagon head fasteners with a relieved shank and long thread configuration as used in aerospace assemblies.
- Strength classification: Rated 1 275 MPa at ambient temperature with performance defined for use up to 650 °C.
- Surface finish: Silver plating specified for the external surface to address mating, corrosion and assembly considerations typical in aerospace environments.
- Intended aerospace use: Characteristics are tailored to aircraft and spacecraft fastener requirements where high temperature performance and reliable clamping are critical.
- Documentation and identification: The standard governs the characteristics manufacturers and purchasers should expect; it supports consistent specification, procurement and inspection practices.
(Note: EN 3009:1998 text is authoritative for exact dimensional, mechanical and marking details - consult the official document for manufacturing tolerances and test methods.)
Practical applications
- Use in high‑temperature aerospace structures and propulsion systems where Inconel 718 strength and heat resistance are required.
- Fastening critical components exposed to elevated temperatures (up to 650 °C) such as engine mounts, hot‑section brackets and high‑temperature housings.
- Procurement and quality control specification: engineering teams, purchasers and inspection authorities cite EN 3009:1998 to ensure correct material, form and plating for service conditions.
- Replacement and maintenance: maintenance manuals and overhaul procedures reference the standard to select compatible OEM replacement bolts.
Who uses this standard
- Aerospace designers and stress engineers specifying high‑temperature fasteners.
- Fastener manufacturers and heat‑treatment suppliers producing NI‑P100HT (Inconel 718) bolts.
- Procurement officers and quality inspectors ensuring compliance with aerospace material and finish requirements.
- Maintenance, repair and overhaul (MRO) organizations sourcing correct replacement hardware.
