Value Collection B7SN0500500CP Threaded Stud Nut 1/2-13 5in B7

Product Description

The VALUE COLLECTION B7SN0500500CP is a fully threaded stud and nut assembly built to ASTM A193 Grade B7 specifications. Each stud measures 1/2-13 thread size and 5 inches in overall length, manufactured from alloy steel with an uncoated finish. The Grade B7 designation indicates high-strength, heat-treated alloy steel suitable for demanding bolting applications including pressure vessels, flanges, and structural connections. The 7B thread fit class ensures controlled tolerance for reliable mating with standard heavy hex nuts. Each package includes 4 studs and 8 nuts, ready for immediate installation by millwrights, pipefitters, and mechanical contractors.

These threaded studs are used in industrial and commercial applications requiring high-strength fasteners, including piping flange assemblies, pressure equipment, heat exchangers, and structural bolting. The ASTM A193 standard makes these appropriate for elevated temperature and high-pressure service environments. They are commonly installed by pipefitters, boilermakers, and industrial maintenance technicians working in process piping, petrochemical, and power generation facilities.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 requirements for high-strength fastener service
• 1/2-13 UNC thread size with 7B class of fit for controlled thread tolerance
• 5 inches overall length suits standard flange bolting and structural connections
• Uncoated finish suitable for applications where coatings would interfere with torque values or require field treatment
• Package includes 4 studs and 8 nuts for complete installation-ready assemblies

Compatibility

Designed for use in ASTM A193-compliant bolting applications where Grade B7 alloy steel studs are specified, including ASME flanged piping systems and pressure vessel connections requiring 1/2-13 thread fasteners.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical technician familiar with ASME and ASTM fastener standards. Always derate torque specifications per the applicable engineering documents or flange bolt-up procedures for the service conditions involved. Ensure mating nut threads and flange bolt holes are clean and free of debris before assembly. Follow applicable codes including ASME B31.3 or the relevant piping or pressure vessel code for the installation site.
