The B7 grade steel stud bolt with a 1/2-inch diameter and 14 cm length weighs approximately 0.25 kilograms. Its material is a chromium-molybdenum alloy steel, quenched and tempered, providing high mechanical strength. The effective thread length is about 35 millimeters, and the thread depth is around 1.2 millimeters. The thread pitch follows the standard 1.27 millimeters, designed according to ANSI/ASME B1.1 to ensure uniform stress distribution in the joint.

The Brinell hardness of the B7 stud bolt ranges from 300 to 350 HB, providing excellent wear and fatigue resistance. Its tensile strength is approximately 1150–1200 MPa, supporting axial loads up to 48 kN. The alloy composition and heat treatment enhance service life and maintain stability under demanding industrial conditions.

Mechanical properties include high tensile strength, adequate hardness, and the ability to withstand dynamic and static loads. Effective thread length and depth ensure proper load capacity in industrial connections. Proper installation with lubrication ensures uniform stress distribution, reducing stress concentration and maintaining safe and reliable long-term performance of the stud bolt.
