SIST EN 4356:2009 - Aerospace series - Six lobe recess - Drivers, short

Overview

EN 4356:2006 is a European standard developed by CEN specifying the technical characteristics of short drivers with a six lobe recess designed for aerospace applications. These drivers are critical tools used in the aerospace industry for fastening components with six lobe security recesses, ensuring precise and reliable torque application essential for aircraft safety and performance. The standard outlines the dimensional, material, marking, and design requirements for these specialized drivers, helping manufacturers and users maintain consistency and quality across aerospace tooling.

Key Topics

  • Scope: Defines the characteristics applicable to short drivers featuring a six lobe recess used in aerospace fasteners.
  • Dimensions and Tolerances: Detailed specifications for driver lengths, widths, and tip configurations are provided with exact millimeter measurements and allowable tolerances to ensure interchangeability and performance consistency. This includes driver tip dimensions for a range of recess codes.
  • Materials: While the material choice is left to the manufacturer, drivers must meet the performance requirements specified in EN 4359, ensuring durability and proper torque transmission.
  • Designation and Marking: Standardized designation formats and marking styles conforming to EN 2424 are defined for clear identification, facilitating traceability and compliance.
  • Normative References: The standard references related aerospace and assembly tools standards like ISO 1173 (drive ends dimensions and torque testing) and EN 4359 (technical specifications for drivers).

Applications

EN 4356:2006 short drivers with six lobe recesses are essential tools in aerospace manufacturing and maintenance, as they:

  • Enable secure fastening of six lobe recess screws and bolts in aircraft structures and components.
  • Promote uniform assembly quality through standardized driver dimensions and torque compatibility.
  • Are critical in environments requiring high reliability and precision such as aerospace manufacturing, repair, and inspection tasks.
  • Support aerospace manufacturers and maintenance providers in complying with international quality and safety standards.

Using drivers standardized under EN 4356 minimizes risks of fastener damage or improper tightening, contributing to aircraft safety and operational efficiency.
