Product Description
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.
Leader-Fastener® 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—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
