Overview
EN 2935:1996 (CEN) defines the characteristics of aerospace T-head bolts with a relieved shank and long thread manufactured from the heat-resisting nickel-base alloy NI-P101HT (Waspaloy). The standard classifies these fasteners for demanding environments by specifying a mechanical classification of 1210 MPa at ambient temperature and elevated-temperature capability to 730 °C. This standard supports the consistent selection and procurement of high-temperature aerospace fasteners.
Key Topics
- Scope: Applies to T-head bolts with relieved shank and long thread made from NI-P101HT intended for aerospace use.
- Material: Heat-resisting nickel-base alloy NI-P101HT (Waspaloy)-selected for high strength and stability at elevated temperatures.
- Classification: Mechanical performance indicated as 1210 MPa at ambient temperature and rated for 730 °C service conditions.
- Design features: T-head geometry, relieved shank for clearance, and extended thread length for specific assembly requirements.
- Quality and consistency: Provides a common reference for manufacturers, procurement teams, and design engineers to ensure material and performance uniformity.
Applications
EN 2935:1996 is focused on aerospace fasteners where high temperature resistance and sustained mechanical strength are essential. Typical practical uses include:
- Engine and hot-section assemblies where nickel-base alloys are required for thermal stability.
- Structural joints exposed to sustained elevated temperatures in aerospace platforms.
- Maintenance and replacement parts where conformity to a recognized standard ensures interchangeability and traceability.
Benefits for engineers and procurement:
- Reliability: Clear classification supports selection of fasteners that maintain integrity at high temperature.
- Compatibility: Standardized characteristics ease integration with aerospace designs and maintenance practices.
- Traceability: Using a CEN standard supports quality assurance and regulatory compliance in supply chains.
Related Standards
For comprehensive specification and application, EN 2935:1996 is commonly used alongside:
- Material specifications and acceptance criteria for nickel-base alloys.
- General aerospace fastener standards covering dimensions, heat treatment, and testing methods.
- Aerospace quality and procurement standards that govern traceability and certification.
When specifying fasteners for high-temperature aerospace use, reference EN 2935:1996 to ensure that T-head bolts made from NI-P101HT (Waspaloy) meet the required performance classification of 1210 MPa at ambient temperature and reliable service up to 730 °C.
