SS316 Stud bolt also known as B8M Stud bolt
The most common standard for flange stud bolt is ASME B18.31.2.
Our SS316 threaded rods are manufactured with high-quality Stainless Steel 316, meeting ASTM A193 B8M Class 2 standards. These rods are designed for construction and maintenance purposes, particularly suited for desalination plants where corrosion resistance is essential.
SS316 Stud bolt is commonly used in marine and other heavy industrial environments that require corrosion resistant fasteners to be used.
SS316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance.

Reference standard:
ASME B18.31.2 Continuous Thread Studs
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 — 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
