Overview
EN 4673-006:2010 is a CEN aerospace standard that defines the characteristics of self-locking inserts with UNJ threads and self-broaching keys manufactured in heat-resisting steel FE-PA2601 (A286) and coated with MoS2 lubricant. The standard is intended for Inch series aerospace applications where high tensile strength and elevated-temperature performance are required. Classification provided in the document is 900 MPa / 315 °C.
Key Topics
- Scope and purpose: Specifies geometry, tolerances, masses and required characteristics for normal and repair-size inserts with self-broaching keys for UNJ threads.
- Material and heat treatment:
- Inserts manufactured to EN 3639 and EN 2399 specifications and treated to a hardness of 370 HV to 435 HV.
- Keys to be made from stainless steel or nickel alloy with hardness > 600 HV.
- Surface treatment: MoS2 dry lubricant coating in accordance with EN 2491; dimensions are given before coating.
- Sizing and dimensions: Normal, first-repair and second-repair insert sizes and external thread dimensions conform to ISO 3161 and the tables in the standard (see Tables 1–4 of EN 4673-006:2010).
- Marking and identification: Marking follows EN 2424 (style F) and manufacturers’ marks conform to TR 3198 guidance.
- Related procedural guidance: Installation/removal and design procedures are referenced to EN 4673-001 and EN 4673-002 respectively; technical specification is EN 4673-003.
Applications
This standard is targeted at aerospace manufacturers, maintenance organizations and fastener suppliers who require:
- Reliable thread insert solutions for UNJ thread interfaces in high-strength, high-temperature environments.
- Standardized normal and repair insert sizes to support maintenance and overhaul operations.
- Components compatible with established EN 4673 series procedures for design, installation and technical specification.
Practical benefits include consistent mechanical performance (900 MPa class), elevated temperature resistance up to 315 °C (as conditioned by the MoS2 lubricant), and harmonized marking and identification for quality traceability.
