Application Summary AI generated
This standard specifies the dimensions, tolerances, and technical requirements for double-end studs with a nominal thread engagement length (bm) of 1.25 times the nominal diameter (d). It is applied in mechanical engineering and assembly contexts where studs are used to create threaded connections between components, particularly when one side requires a longer thread engagement for strength or material compatibility. The standard ensures interchangeability and reliability in applications such as automotive, industrial machinery, and structural fastening systems.
