General Information
Overview
EN 2413:1995 is a CEN aerospace standard that defines the characteristics of a specific class of high‑strength bolts: shouldered, thin hexagonal head bolts with a close tolerance shank and short thread, manufactured in alloy steel and cadmium plated. The standard gives a mechanical classification of 1100 MPa (at ambient temperature) / 235 °C, and specifies that these bolts are intended to be used together with washers EN 2414 and nuts EN 2415. EN 2413:1995 is published as SIST EN 2413:2001 in the Slovenian catalogue.
Key Topics
The standard addresses the following technical topics and requirements:
- Bolt form and geometry: definition of the shouldered design, thin hexagonal head shape, close‑tolerance shank, and short threaded portion to ensure fit and load transfer in aerospace assemblies.
- Material specification: requirement for alloy steel construction to meet the high‑strength classification.
- Surface treatment: cadmium plating as the specified corrosion‑resistant finish for the bolt.
- Mechanical classification: performance class noted as 1100 MPa at ambient / 235 °C, indicating intended high‑strength use and elevated temperature capability.
- Interchangeability: compatibility requirements with washers EN 2414 and nuts EN 2415, ensuring component matching in assemblies.
- Intended application domain: aerospace series fasteners where size, strength, and fit are critical.
(EN 2413:1995 focuses on characteristics and compatibility; for full normative details - dimensions, tolerances, testing and marking - consult the full published standard.)
Applications
Who uses EN 2413:1995 and where it applies:
- Aerospace OEMs and suppliers specifying high‑strength fasteners for aircraft and spacecraft structural assemblies.
- Design engineers selecting shouldered bolts for precision fits, shear load locations, or components requiring close‑tolerance shank engagement.
- Procurement and quality teams ensuring purchased bolts meet the CEN classification, material, and plating requirements.
- Maintenance, repair and overhaul (MRO) operations that need replacement parts compatible with EN 2414 washers and EN 2415 nuts. Practical uses include structural joints, fitted dowel applications, and locations where controlled bearing surfaces and short thread length are required.
