Overview
EN 4495:2006 is a European standard issued by CEN that specifies the characteristics of aerospace bolts with a normal hexagonal head, close tolerance normal shank, and short thread. These bolts are made from titanium alloy, anodized, and coated with an aluminium pigmented layer, designed to meet stringent aerospace performance requirements. Classified for strength at 1,100 MPa ambient tensile strength and capable of withstanding temperatures up to 315 °C, this standard addresses high-performance fasteners essential for aerospace applications.
This document ensures uniformity in bolt manufacturing and quality, offering reliability in aerospace assemblies where material strength, durability, and resistance to harsh environments are critical.
Key Topics
- Bolt Characteristics: Normal hexagonal head, close tolerance normal shank, short thread dimensions according to metric series.
- Material Specification: Titanium alloy with a minimum tensile strength of 1,100 MPa at ambient temperature, providing excellent strength-to-weight ratio.
- Surface Treatment: Anodizing combined with an aluminium pigmented coating for enhanced corrosion resistance and durability.
- Temperature Classification: Bolts retain original mechanical properties up to 315 °C, ensuring performance in elevated temperature conditions.
- Dimensional Standards: Compliant with ISO 3193 and ISO 7913 for bolt geometry, form, and positional tolerances.
- Marking and Identification: Bolts carry specific markings in line with EN 2424 for traceability and quality assurance.
- Manufacturing and Quality Control: Manufacturer approval and bolt qualification follow EN 9100 and EN 9133 quality management requirements.
Applications
EN 4495 bolts are primarily used in aerospace engineering where reliability, lightweight properties, and high strength under both normal and elevated temperature conditions are mandatory. Typical applications include:
- Aircraft Structural Assemblies: Securing critical airframe components exposed to mechanical stress and temperature variations.
- Engine Components: Bolts withstand high thermal loads in engine assemblies thanks to their titanium alloy composition and coatings.
- Spacecraft and Satellites: The anodized aluminium pigmented coating provides corrosion resistance essential for harsh space environments.
- High-precision Aerospace Equipment: Close tolerance shank and thread ensure accurate fit and superior mechanical integrity.
Their enhanced coating and material properties extend the longevity and safety of aerospace fasteners, contributing to overall aircraft reliability and performance.
Related Standards
EN 4495:2006 references and aligns with several other key aerospace and fastener standards to provide comprehensive specifications for bolt performance and usage:
- ISO 3193: Defines dimensions for aerospace bolts with hexagonal heads and short or medium-length MJ threads.
- ISO 3353-1: Specifies rolled external threads for aerospace lead and runout threads.
- ISO 7913: Tolerances of form and position for metric bolts and screws.
- ISO 9152: Procurement specifications for titanium bolts with MJ threads, strength class 1,100 MPa.
- EN 2424: Marking requirements for aerospace products to ensure traceability.
- EN 4474: Details aluminium pigmented coating methods applicable to these bolts.
- EN 9100 and EN 9133: Quality management systems ensuring manufacturer competence and product qualification.
- EN 4016: Guidelines for oversized bolts applicable in aerospace contexts.
- MIL-L-87132B: Lubrication specifications relevant to bolt application.
By adhering to these interconnected standards, EN 4495 bolts meet rigorous aerospace industry demands, ensuring performance, safety, and regulatory compliance across the European Union and beyond.
