Scope

Standardization of fasteners and fastened connections, including:

  • terms and definitions,​
  • dimensions and tolerances,​
    • ​
  • mechanical, physical and functional properties,​
    • ​
  • fastener coatings and finishes,​
    • ​
  • test methods,​
    • ​
  • acceptance and quality procedures,​
    • ​
  • design and calculation of fastened assemblies/joints,​
    • ​
  • assembly methods,​
    • ​
  • assembly/joint qualification.

    • The term fastener covers all types of products designed to mechanically join two or more parts to form a solid or movable fastened connection or to contribute essentially to establish this function, such as bolts, screws, nuts, washers, pins and rivets.

    Assembly/joint qualification includes qualification of the assembly/joint, the assembly tools as well as the qualification of the personnel.

    Excluded:

  • Fasteners for aerospace applications, keys, and hose clamps.
