General Information
Overview
EN 6024:2024 is a CEN aerospace standard that specifies the characteristics for a specific high‑strength, inch‑series screw: 100° countersunk reduced head, offset cruciform recess, close‑tolerance shank, short thread, made from titanium alloy, anodized and MoS2 (molybdenum disulphide) lubricated. The screw is classified for a minimum tensile strength of 1 100 MPa (at ambient temperature) and a maximum service temperature of 315 °C. This document covers configuration, dimensions, materials, surface treatment, marking, testing and quality requirements for aerospace applications.
Key Topics and Requirements
- Geometry & dimensions: Detailed configuration, tolerances and mass values are provided (figures and tables given in the standard). Thread form and limits follow ISO 3161 (UNJ threads); thread runout per ISO 3353‑1.
- Recess & drive: Offset cruciform recess specified per NASM 33781; torque testing for installation/removal with axial end pressure ≤ 68 N.
- Material: Titanium alloy requirements referenced to EN 2532:1996‑12 or TR 3775; material code options and head‑strength considerations (code “K”) noted.
- Surface treatment & lubrication: Anodizing thickness and surface roughness requirements, with MoS2 dry lubricant application per EN 2491 (5–10 µm coating specification).
- Mechanical testing: Tensile loads and fatigue requirements are defined (fatigue test load = 33.3% of tabulated tensile load); bolts rejected for fracture or allowable distortion criteria following the standard.
- Designation & marking: Part numbering per ATA iSpec 2200 and marking per EN 2424, style B.
- Quality & qualification: Manufacturer must be an approved aerospace production organization with a documented quality management system (e.g., EN 9100) and product qualification per EN 9133 or equivalent.
Applications and Users
Who uses EN 6024:2024:
- Aerospace fastener manufacturers and suppliers (titanium screw production, anodizing, MoS2 coating)
- Aircraft design and stress engineers specifying flush, high‑strength titanium fasteners
- Maintenance, repair and overhaul (MRO) organizations ensuring correct replacement parts and torque procedures
- Procurement and quality assurance teams validating supplier conformance and part marking
Typical use cases:
- Flush structural assemblies and panels where 100° countersunk fasteners provide aerodynamic or clearance benefits
- High‑strength, lightweight fastening in airframe, engine accessory or thermal environments up to 315 °C
- Applications requiring precise drive engagement with offset cruciform recess and controlled torque/installation behavior
