Value Collection B7SN0500450CP Threaded Stud Nut 1/2-13 Steel

Product Description

The VALUE COLLECTION B7SN0500450CP is a fully threaded stud and nut fastener assembly designed for high-strength bolted connections in industrial and mechanical applications. Each stud measures 4.5 inches in length with a 1/2-13 thread size and is manufactured from alloy steel to ASTM A193 Grade B7 standards. The 7B thread fit class ensures a controlled thread tolerance suited for critical joint applications. This package includes four studs and eight nuts, supplying complete fastener sets for multiple connection points. Installed by millwrights, pipefitters, and maintenance mechanics, these studs are a standard choice where high tensile strength and reliable clamping force are required.

Grade B7 threaded studs are widely used in pressure vessel flanges, pipe flanges, structural assemblies, and heavy equipment connections across industrial, commercial, and process-industry settings. The uncoated finish is typical for applications where additional coatings or platings will be applied on-site, or where bare alloy steel is acceptable per the applicable specification. The ASTM A193 standard governs these fasteners for high-temperature and high-pressure service environments.

Key Features

• 1/2-13 thread size with 7B thread fit class for controlled tolerance
• 4.5 inches overall stud length for standard flange and structural applications
• ASTM A193 Grade B7 alloy steel construction for high tensile strength
• Uncoated finish suitable for bare-steel service or field-applied coatings
• Includes four studs and eight nuts per package for complete fastener sets
• Fully threaded along entire stud length for maximum engagement flexibility

Compatibility

Designed as a standard-specification replacement or new-installation fastener for 1/2-13 threaded flange, structural, and pressure-boundary connections requiring ASTM A193 Grade B7 alloy steel studs.

Installation Notes

Installation is performed by qualified millwrights, pipefitters, or maintenance mechanics following applicable codes such as ASME PCC-1 for pressure-boundary bolted joints. De-energize, depressurize, and isolate the assembly before removing or installing studs. Use a calibrated torque wrench and follow the joint-specific torque sequence defined in the applicable engineering specification. Do not mix Grade B7 studs with incompatible nut grades in critical pressure or high-temperature applications.
