Value Collection B7SN1000525CP Threaded Stud Nut 1-8 B7

Product Description

The VALUE COLLECTION B7SN1000525CP is a fully threaded stud with nut, manufactured from Grade B7 alloy steel in an uncoated finish. Each stud measures 1-8 thread size and 5.25 inches in length, with a 7B class of fit for precise thread engagement. Conforming to ASTM A193 standards, this stud is engineered for high-strength bolting applications where reliable clamping force and dimensional consistency are critical. Each package contains four studs and eight nuts, making it suitable for flange assemblies, pressure vessel work, and structural connections commonly handled by industrial maintenance technicians, pipefitters, and mechanical contractors.

This fully threaded stud is designed for industrial and commercial bolting applications including flange joints, pipe connections, pressure vessel assemblies, and structural mechanical work. The Grade B7 alloy steel construction provides the tensile strength required in high-load or elevated-temperature service environments. The 7B thread fit class ensures consistent engagement and reliable torque transfer across mating components. Each package includes four studs and eight nuts, supplying a complete fastener set for multi-bolt flange applications.

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for industrial flange, pressure vessel, and structural bolting applications requiring 1-8 fully threaded studs conforming to ASTM A193 Grade B7 specifications.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical technician following applicable ASME, ASTM, or plant-specific torque and assembly procedures. Depressurize and isolate any piping or pressure vessel before removing or installing flange fasteners. Inspect threads on both studs and nuts for damage before assembly, and apply thread lubricant or anti-seize compound as required by the service specification. Do not mix Grade B7 studs with non-compatible nut grades in pressure-rated assemblies.
