Value Collection B7SN0880825CP Stud Nut 7/8-9 Steel B7

Product Description

The VALUE COLLECTION B7SN0880825CP is a fully threaded stud and nut assembly manufactured to ASTM A193 Grade B7 specifications. Each stud measures 7/8-9 thread size and 8.25 inches in length, cut from alloy steel left uncoated for use in high-temperature and high-pressure bolting applications. The Grade B7 material designation meets ASTM A193 requirements, making this assembly a standard choice in flanged piping, pressure vessel, and structural bolting work. Licensed plumbers, pipefitters, and mechanical contractors who need a reliable, spec-compliant threaded fastener will find this assembly ready to install without additional hardware sourcing.

This stud and nut assembly is suited for industrial and commercial applications including bolting pipe flanges, pressure vessel covers, heat exchangers, and structural connections where high-strength alloy steel is required. The 7B class of fit ensures proper thread engagement with standard heavy hex nuts. Each package includes four studs and eight nuts, providing complete hardware for multiple flange connections in a single purchase. Applications span HVAC mechanical rooms, process piping, and utility plant work where ASTM A193 compliance is specified by the engineer of record.

Compatibility

Designed as a standard ASTM A193 Grade B7 fully threaded stud assembly for use in flanged pipe connections, pressure vessels, and structural bolting applications requiring 7/8-9 thread size.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or mechanical contractor following applicable ASME B31 piping codes and project-specific torque specifications. De-energize, depressurize, and isolate the system fully before removing or installing any flange fasteners. Apply thread lubricant or anti-seize compound as required by the engineering specification before tightening. Inspect threads for damage and verify nut engagement across the full stud length before applying final torque.
