This Standard covers the complete dimensional and general data for continuous thread, flange studs (stud bolts), and double-end inch-dimensioned studs. The following configurations are covered: Continuous thread stud: studs that are threaded over their complete length. Flange stud (stud bolt): threaded studs used primarily in applications with flanges covered by ASME B16.5, and made using ASTM A01 bolting materials. Double-end stud (clamping type \u2014 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 (b) Full body The inclusion of dimensional data in this Standard is not intended to imply that all products described are stock production items. Consumers should consul t w it h suppliers concerning availability of products.<\/p>\n
