ASME B18.31.2

Abstract

This Standard covers the complete dimensional and general data for the following types of studs in inch dimensions: <br><em>(a)</em> continuous thread studs <br><em>(b)</em> double-end studs <br><em>(c)</em> flange bolting studs (stud bolts) <br>These studs are recognized as American National Standard. The following configurations are covered: <br><em>continuous thread stud:</em> a stud that is threaded over its complete length. <br><em>double-end (clamping type &#8212; identical ends) stud:</em> a stud 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. <br><em>double-end (tap-end type) stud:</em> 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. <br>Double-end studs of the following body diameters are covered: <br>(a) reduced-diameter body (see para. 6.1 for dimensions) <br>(b) full body (see para. 6.2 for dimensions) <br><em>flange bolting stud (stud bolt):</em> a threaded stud used primarily in applications with flanges covered by ASME B16.5, and made using ASTM A01 bolting materials. <br>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.
