Overview
SIST EN 3015:2015 is a European Standard developed by CEN under the aerospace series, focusing on the specifications for shank nuts that are self-locking, serrated, and manufactured from heat-resisting FE-PA2601 (A286) steel, silver-plated for enhanced performance. This standard establishes the essential characteristics and performance requirements for these specialized fastening components, designed specifically for demanding aerospace environments where strength, durability, and resistance to high temperature are critical.
The standard specifies shank nuts with:
- Self-locking serrated design for vibration resistance
- FE-PA2601 (A286) heat-resisting steel for improved mechanical and thermal properties
- Silver plating to enhance corrosion resistance and facilitate assembly
- Classification: 1 100 MPa minimum tensile strength at ambient temperature, and integrity up to 650 °C
Key Topics
- Product Characteristics
- Defines the required configuration, dimensions, tolerances, and mass for shank nuts
- Specifies material requirements based on EN 2399 or EN 3639 standards for FE-PA2601
- Performance Criteria
- Minimum tensile strength of 1 100 MPa at room temperature
- Operational capability up to 650 °C, suitable for high-temperature aerospace applications
- Designation & Identification
- Standardizes the method for identifying parts, including marking in accordance with EN 2424
- Includes a clear system for thread size and nut configuration designation
- Installation Guidance
- References installation procedures ensuring secure fit and performance
- Highlights the importance of installation hole design and notch sensitivity
Applications
SIST EN 3015:2015 shank nuts are intended for use in aerospace engineering, where reliability and safety are non-negotiable. Common applications include:
- Aircraft structural assemblies: Used in areas subject to intense vibration and thermal variation
- Engine and exhaust systems: Where exposure to elevated temperatures and mechanical stress is routine
- Aerospace equipment and components: Such as landing gear, airframe, and engine mounts requiring secure, self-locking fastening solutions
The self-locking serrated design helps prevent loosening due to vibration, a critical requirement in aviation and aerospace. Use of FE-PA2601 (A286) ensures the nuts maintain performance in extreme conditions.
