This standard covers the complete dimensional and general data for continuous thread and double end metric series studs recognized as an American National Standard. The following configurations are covered: continuous thread stud: studs that are threaded over their complete length. double end stud (clamping type): studs with screw threads of the same length and configuration on each end. This type of stud serves the function of clamping two bodies together with a nut on each end. double end stud (tap end type): a stud designed to be installed in a tapped hole and usually with different threaded lengths on each end. The tap end studs covered by this standard have the same thread form on each end with the length of the tap end threads equal to approximately 1-1/2 times the nominal thread diameter.
