Overview

EN 2887:1995 (adopted as SIST EN 2887:2001) is a CEN aerospace standard that specifies the characteristics of normal hexagonal‑head bolts threaded to the head, made from corrosion‑resisting steel and passivated. The standard defines a mechanical classification of 600 MPa (at ambient temperature) with performance referenced to 425 °C, targeting aerospace applications that require both corrosion resistance and elevated‑temperature capability.

Key topics and requirements

The standard concentrates on the following core characteristics:

• Bolt geometry: normal hexagonal head form with threads extending close to or up to the head ("threaded to head").
• Material: corrosion‑resisting (stainless) steel suitable for aerospace use.
• Surface treatment: passivation to enhance corrosion resistance and reduce risk of contamination.
• Mechanical classification: defined tensile/strength class 600 MPa at ambient, with classification related to behaviour up to 425 °C.
• Scope of specification: formal designation, identification, and the essential characteristics that manufacturers, purchasers and certification authorities need when specifying these fasteners.

Note: EN 2887:1995 sets out the characteristics required; detailed dimensional tables, tolerance, test methods, purchase documentation or acceptance criteria may be referenced or cross‑checked with other fastener standards and industry practice.

Applications

EN 2887 bolts are intended for aerospace structural and equipment assemblies where:

• Corrosion resistance is required (marine, humid or chemically exposed environments).
• Elevated‑temperature performance up to 425 °C is a design consideration.
• The assembly requires hexagonal‑head bolts with threads extending to the head for clamping in confined or thin sections.

Who uses this standard:

• Aerospace design engineers specifying fasteners for airframe and equipment
• Fastener manufacturers and heat‑treat/passivation processors
• Procurement and quality assurance teams verifying conformity
• Maintenance, repair and overhaul (MRO) organizations replacing specified fasteners

Related standards

• Other EN and ISO fastener standards covering mechanical classes, dimensions, thread forms and test methods are typically used alongside EN 2887 to complete procurement and inspection specifications.
• Users should cross‑reference applicable aerospace material, heat‑treatment and surface‑treatment standards when preparing purchase orders or inspection plans.
