Value Collection B7SN0880450CP Threaded Stud Nut 7/8-9 4.5in Steel

Product Description

The VALUE COLLECTION B7SN0880450CP is a fully threaded stud and nut assembly manufactured from alloy steel to ASTM A193 Grade B7 specifications. Each stud measures 7/8-9 thread size and 4.5 inches in length, with a 7B class of fit for the mating nuts. The uncoated finish exposes the base steel, making these studs well-suited for high-temperature and high-pressure bolting applications where dimensional accuracy and material strength are the priority. This package includes 4 studs and 8 nuts. Pipefitters, millwrights, and industrial maintenance mechanics commonly install these fasteners in flanged connections, pressure vessels, and structural assemblies.

These Grade B7 studs are a standard choice for flanged pipe joints, heat exchangers, pressure vessels, and structural bolting in industrial, commercial, and utility plant environments. The 7/8-9 thread is a coarse-series designation widely used in heavy mechanical assemblies. The 7B thread fit class is specified for general-purpose external thread applications requiring reliable engagement under load. No field machining or modification should be needed when matching to properly tapped or nutted connections of the same thread designation.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength, high-temperature service
• 7/8-9 thread size with 7B class of fit for consistent thread engagement
• 4.5-inch full-thread length provides maximum engagement flexibility
• Uncoated finish — no coating buildup that could affect thread tolerance
• Package includes 4 studs and 8 nuts, ready for direct installation

Compatibility

Designed as a standard Grade B7 fully threaded stud for use in ASTM A193-compliant bolting applications requiring 7/8-9 thread size and 4.5-inch length.

Installation Notes

Installation of ASTM A193 Grade B7 studs is typically performed by licensed pipefitters or millwrights in accordance with applicable ASME and ASTM bolting standards. Confirm thread class compatibility with mating nuts before installation. De-energize, depressurize, and isolate any system before disassembling or replacing fasteners in pressurized service. Do not substitute Grade B7 studs in applications requiring a different material grade without engineering review.
