Application Summary AI generated
This standard specifies the dimensions, technical requirements, and marking of hexagon head bolts with a split pin hole on the head and a reduced shank, classified as product grade B. It is applied in mechanical assemblies where bolts require a locking mechanism via a split pin through the head, and the reduced shank is used to save weight or accommodate clearance in applications such as automotive, agricultural machinery, and general industrial equipment. The standard ensures interchangeability and reliability in fastening systems where moderate precision (grade B) is acceptable.
