Value Collection B7S087C450 Threaded Stud 7/8-9 4.5in Grade B7

Product Description

The VALUE COLLECTION B7S087C450 is a fully threaded stud with a 7/8-9 thread form and an overall length of 4.5 inches. Manufactured from Grade B7 alloy steel in an uncoated finish, this stud carries a Class 2A thread fit for standard external thread tolerance applications. The full-thread design means the stud engages a nut or tapped hole along its entire length, maximizing grip and load-bearing capacity. It is a common fastener used by mechanical contractors, industrial maintenance techs, pipefitters, and equipment installers in structural and mechanical assemblies.

This stud is suited for applications that require a high-strength fastener in steel construction, pipe flanges, mechanical equipment mounting, and general industrial assembly. The Grade B7 material designation indicates medium-carbon alloy steel with elevated tensile strength, making it appropriate for demanding environments including elevated-temperature service in piping systems and pressure equipment. Its 7/8-9 UNC thread is a widely used coarse-thread size in industrial fastener standards.

Key Features

• Fully threaded along the entire 4.5-inch overall length for maximum thread engagement
• Grade B7 alloy steel provides high tensile strength for demanding structural and mechanical applications
• 7/8-9 UNC coarse thread form with Class 2A fit for standard tolerance external thread assemblies
• Uncoated finish suitable for use as-is or with customer-applied coatings or lubricants
• Compact single-piece stud form with no shoulder or reduced shank

Compatibility

Designed as a standard-tolerance Grade B7 fully threaded stud for use in industrial, mechanical, and piping flange assemblies requiring a 7/8-9 UNC coarse-thread fastener.

Installation Notes

Installation of threaded studs in pressure equipment or pipe flanges is typically performed by licensed pipefitters or mechanical contractors following applicable codes such as ASME B16.5 or ASME PCC-1 for bolted flange joints. Power down and de-energize or de-pressurize any system before servicing fasteners in live assemblies. Use calibrated torque equipment when specified by the equipment manufacturer or applicable code; do not substitute thread lubricant type without verifying with the applicable specification. Inspect threads for damage before installation and confirm nut or tapped-hole thread class matches the stud.
