General Information
Relations
Overview
EN 2859:2006 is a European standard developed by CEN that specifies the characteristics of aerospace-grade bolts with a normal hexagonal head, close tolerance normal shank, and short thread. These bolts are made from alloy steel, are cadmium plated, and conform to the metric series. The standard classifies these bolts with a minimum tensile strength of 1,100 MPa at ambient temperature and resistance up to 235 °C. Designed specifically for aerospace applications, EN 2859:2006 ensures high-quality mechanical performance, precise dimensions, and strict surface treatment requirements to maintain safety and reliability in demanding environments.
Key Topics
Scope and Classification
EN 2859:2006 covers bolts that must meet strength requirements of 1,100 MPa at room temperature and maintain function up to 235 °C, crucial for aerospace structures exposed to varying operating conditions.Dimensions and Tolerances
Bolt dimensions follow the aerospace metric series defined in ISO 3193, including close tolerance specifications for shank diameter and short thread length configurations. Form and position tolerances align with ISO 7913 for accurate fit and assembly.Materials and Surface Treatment
Constructed from alloy steel per aerospace-grade specifications (TR 3775), bolts require a cadmium plating thickness of 6 µm to 10 µm on critical contact surfaces for corrosion resistance. An optional black coloration code (B) is also defined for special applications without compromising coating integrity.Marking and Designation
Bolts are marked according to EN 2424 with identification codes denoting diameter, length, hole configurations, and surface finish. The designation system simplifies procurement and traceability by providing standardized code blocks.Technical Requirements
Compliance with aerospace procurement and quality management standards such as EN 9100 and EN 9133 is mandatory, ensuring manufacturer approval and bolt qualification under strict aerospace criteria. Oversized bolt specifications are referenced to EN 4016.
Applications
Aerospace Manufacturing and Maintenance
EN 2859 bolts are applied extensively in aircraft assembly, engine components, and structural frameworks where high tensile strength and environmental resistance are essential.High-temperature Environments
Suitable for aerospace applications requiring reliability at temperatures up to 235 °C, such as near engines or hydraulic systems.Critical Mechanical Fastening
Used in safety-critical joints where precise tolerance, strength, and corrosion resistance maintain the integrity of airframes and aerospace assemblies.
