1.1.1 This Standard covers the complete dimensional and general data for continuous thread and double-end inch-dimensioned studs recognized as American National Standard. The following configurations are covered:

continuous thread stud: studs that are threaded over their complete length.

double-end stud (clamping type – identical ends): 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. For the tap end of the studs, both regular unified threads and interference-fit threads are covered.

Double-end studs of the following body diameters are covered:
a. reduced diameter body (see para. 6.1 for dimensions)
b. full body (see para. 6.2 for dimensions)

1.1.2 The inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Consumers should consult with suppliers concerning availability of products.
