Application Summary AI generated

This standard specifies the dimensional, mechanical, and performance requirements for assemblies consisting of a cross recessed raised countersunk head screw combined with a pre-assembled countersunk external toothed lock washer. It is applied in mechanical and electronic product assembly where vibration resistance and a flush or slightly protruding fastener head profile are needed, such as in automotive, appliance, and industrial equipment manufacturing. The standard ensures interchangeability and reliable locking action under dynamic loads, preventing loosening in threaded joints.
