Value Collection B7SN1000550CP Threaded Stud Nut Grade B7

Product Description

The VALUE COLLECTION B7SN1000550CP is a fully threaded stud with nuts, manufactured from alloy steel to ASTM A193 Grade B7 material specifications. Each stud measures 1-8 thread size and 5.5 inches in length, with a 7B class of fit. The uncoated finish is standard for industrial and mechanical fastener applications. This fastener is used by pipefitters, millwrights, and mechanical contractors where high-strength, full-length threading is required in bolted assemblies. Each package includes four studs and eight nuts, providing everything needed for basic installation.

This stud and nut set is suited for industrial piping flanges, pressure vessel assemblies, and structural bolting applications where ASTM A193 Grade B7 alloy steel compliance is specified. The 7B thread fit class indicates a standard tolerance class appropriate for general-purpose high-strength fastener use. Installation is typically performed by licensed pipefitters or millwrights working on pressure systems, process equipment, or structural assemblies. The package quantity of four studs and eight nuts makes this suitable for small-scale jobs or replacement of individual fasteners in an existing bolted connection.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 standards for high-strength fastener applications
• Fully threaded stud design allows flexible engagement depth and versatile installation options
• 7B class of fit provides standard industrial thread tolerance for reliable mating
• Uncoated finish suitable for environments where coatings are not required or where field coating will be applied
• Each package includes four studs and eight nuts for complete fastener sets

Compatibility

Designed for use in industrial bolting applications requiring ASTM A193 Grade B7 alloy steel fully threaded studs with 1-8 thread size and 7B class of fit.

Installation Notes

Installation is typically performed by licensed pipefitters or millwrights in accordance with applicable mechanical and pressure system codes. De-energize and depressurize any system before replacing or installing fasteners in flanged or pressure vessel connections. Use calibrated torque equipment appropriate for the bolt size and joint specification. Do not mix Grade B7 studs with non-compatible nuts or washers that do not meet the required material or thread standards.
