Overview
The oSIST prEN 4162:2024:2024 is a European standard developed by CEN under the ASD-STAN technical committee, specifying the technical characteristics for aerospace screws. This standard governs screws featuring a 100° countersunk normal head with an offset cruciform recess, manufactured from alloy steel with cadmium plating. These screws are classified for mechanical strength at 1,100 MPa tensile strength at ambient temperature and designed to withstand operating temperatures up to 235 °C. The specification aims to ensure consistent quality, reliability, and interchangeability for critical aerospace applications.
Key Topics
Screw Configuration and Dimensions
Defines precise dimensions, head angles, thread details, and mass based on ISO 5856 and related aerospace thread standards. The screws have a medium-length thread, normal shank with coarse tolerance, and specific diameter and length codes to suit varying aerospace requirements.Material and Strength
Screws are fabricated from alloy steel complying with EN 2137 and EN 3514, ensuring a minimum tensile strength of 1,100 MPa. This high-strength alloy steel enhances durability and mechanical performance in demanding aerospace environments.Surface Treatment
Cadmium plating according to EN 2133:2020 is mandatory, providing corrosion resistance and maintaining mechanical properties at elevated temperatures. Several post-treatment passivation options are permitted, including chromate and non-chromium (VI) passivations, identified by specific code letters for traceability.Tolerances and Form
Form and positional tolerances conform with ISO 7913, ensuring dimensional precision essential for aerospace assembly and function.Marking and Designation
Marking conventions follow EN 2424 requirements, including diameter, length, and drive codes for identifying screws unambiguously. The screw designation code enables straightforward ordering and specification matching.Manufacturer Requirements and Quality Assurance
Manufacturing entities must be aerospace production-approved organizations with quality management compliant with EN 9100 or equivalent. Screw qualification must follow rigorous aerospace standards such as EN 9133, guaranteeing product consistency and performance.
Applications
oSIST prEN 4162:2024 screws are specifically designed for aerospace series fastening applications where high strength, precision, and resistance to environmental stresses are critical. Typical use cases include:
- Aircraft structural assembly
- Aerospace components requiring flush fitting with countersunk head design
- Environments demanding resistance to corrosion and temperature variations up to 235 °C
- Critical mechanical fastening in defense and space systems where quality assurance is mandatory
Their medium thread length and offset cruciform drive provide ease of installation while maintaining secure fixation in alloy steel assemblies.
