Overview
EN 3008:1998 is a European standard developed by CEN that specifies the requirements for aerospace-grade bolts featuring a hexagon head, relieved shank, and long thread design. These bolts are manufactured from the heat-resisting base alloy NI-P100HT, commonly known as Inconel 718. This nickel-based superalloy ensures exceptional performance in demanding aerospace environments by maintaining mechanical strength and corrosion resistance at elevated temperatures. The standard classifies these bolts to withstand tensile strengths of 1275 MPa at ambient temperature and retain structural integrity up to 650 °C.
Key Topics
Bolt Design
- Hexagon head for optimal torque application
- Relieved (reduced diameter) shank to minimize stress concentration
- Long-threaded section for greater engagement and adjustability
Material Specification
- NI-P100HT (Inconel 718), a heat-resistant nickel-chromium alloy known for superior strength and oxidation resistance
- Suitable for high-temperature aerospace environments
Mechanical Properties
- Classification at 1275 MPa tensile strength at room temperature
- High-temperature performance certified up to 650 °C
Quality and Testing
- Conformance to strict mechanical and geometric tolerances
- Testing procedures to verify strength, thread integrity, and temperature resistance
Applications
EN 3008:1998 bolts are designed specifically for aerospace and aerospace-related industries requiring reliable fasteners that operate safely under extreme thermal and mechanical stress conditions. Typical applications include:
- Jet engine assemblies where components are exposed to high temperatures
- Structural fastening in aerospace airframes and systems requiring high strength and corrosion resistance
- High-performance aerospace machinery and equipment operating in harsh environments
- Spacecraft hardware exposed to fluctuating thermal loads
Using bolts compliant with EN 3008 ensures enhanced safety, durability, and performance in critical aerospace applications, reducing maintenance and failure risks.
