General Information

Overview
EN 2886:2023 is a European standard developed by CEN specifying the requirements for aerospace series screws featuring a pan head, offset cruciform recess, close tolerance normal shank, and short thread. Made of alloy steel and cadmium plated, these screws are classified to withstand a tensile strength of 900 MPa at ambient temperature and temperatures up to 235 °C without degradation. Replacing the 1996 edition, this updated standard addresses dimensional tolerances, material properties, surface treatments, and marking relevant to aerospace industry applications.
This standard ensures high-quality, precision fasteners critical for aerospace components where reliability, strength, and resistance to thermal stress are vital.
Key Topics
Screw Configuration & Dimensions
Defines detailed geometric parameters, including pan head shape, offset cruciform recess type, normal shank with close tolerances, and short thread metrics. Dimensions adhere to metric specifications and are expressed in millimeters after surface treatment.Material Specifications
Alloy steel with a minimum tensile strength of 900 MPa at ambient temperature is mandated. Surface finishes must comply with cadmium plating thickness between 8 µm and 14 µm, ensuring corrosion resistance and durability in aerospace environments.Thread Characteristics & Tolerances
Thread form and position must comply with ISO 7913 to guarantee fit and function. Thread dimensions follow aerospace series standards (e.g., ISO 3353-1, ISO 5855-2). Short thread lengths optimize performance while maintaining structural integrity.Surface Treatment
Cadmium plating is required on all contact surfaces to protect against corrosion. Specific thickness and surface finish quality criteria ensure consistent plating that withstands operational thermal conditions.Marking and Identification
Marking standards per EN 2424 include diameter codes and drive type indicators for traceability and standardized identification. Markings are indented for durability.Quality Management Requirements
Manufacturers must operate approved quality management systems compliant with aerospace standards such as EN 9100, ensuring consistent product quality and traceability.
Applications
EN 2886:2023 screws are designed specifically for aerospace use in:
- Aircraft structural assemblies requiring high-strength, reliable fastening solutions.
- Components exposed to varied thermal environments up to 235 °C, such as engine parts and airframe fasteners.
- Precision assemblies benefiting from close tolerance dimensions and reliable thread engagement.
- Replacement and maintenance parts where international standard compliance is critical for interoperability and safety.
The standard’s emphasis on tensile strength and plating ensures that these screws remain durable under mechanical load and environmental stresses common in aviation and space applications.
