General Information

Overview
EN 3014 (prEN 3014:2022 - intended to supersede EN 3014:2015) is a CEN aerospace standard that specifies the characteristics of self‑locking, serrated shank nuts manufactured from heat‑resisting steel FE‑PA2601 (A286). Classification for these nuts is 1 100 MPa (ambient) / 650 °C, making them suitable for aerospace components that require high strength and elevated temperature resistance. The standard covers configuration, dimensions, materials, marking, designation, technical specification and installation requirements specific to serrated shank nuts.
Key topics and requirements
- Material: Shank nuts shall be made from heat‑resisting steel FE‑PA2601 (A286) as referenced to EN 2399 or EN 3639.
- Strength and temperature class: Classification given as 1 100 MPa at ambient temperature with maximum test temperature up to 650 °C.
- Geometry and tolerances: Detailed configuration, dimensions, tolerances and masses (in millimetres) are defined; MJ thread limits are aligned with ISO 5855‑2.
- Self‑locking serration: Forming out‑of‑round in the self‑locking zone and serration geometry are specified to achieve locking performance; tooling marks in the formed area are permissible.
- Thread surface and edges: Thread finishes follow normal manufacturing methods; sharp edges to be removed in the 0.1–0.4 mm range.
- Marking and designation: Marking follows EN 2424 (style A) and designation rules are provided for traceability and procurement.
- Installation: Installation procedures and hole design are referenced (EN 3064 and EN 3065); the standard highlights the need to consider notch sensitivity of the host material.
- Normative alignment: Technical specifications and tests reference EN 3004 and related aerospace fastener standards.
Applications and who uses EN 3014
- Applications: Use where a high‑strength, heat‑resistant self‑locking nut is required - e.g., aerospace structural assemblies and components exposed to elevated temperatures up to 650 °C.
- Users: Aerospace fastener manufacturers, design engineers, structural engineers, procurement and quality assurance teams, maintenance and repair organizations (MROs), and test laboratories.
- Benefits: Ensures interchangeability, consistent mechanical performance, traceability and safe installation practice for serrated shank nuts in critical aerospace applications.
