Value Collection B7SN1130725UP Threaded Stud Nut 1-1/8-8

Product Description

The VALUE COLLECTION B7SN1130725UP is a fully threaded stud with nut manufactured from alloy steel to ASTM A193 Grade B7 standards. Each stud measures 7.25 inches in length with a 1-1/8-8 thread size and an uncoated finish. The 7B class of fit provides a standard allowance for general fastening applications. This hardware is commonly installed by pipefitters, millwrights, and industrial maintenance mechanics in bolted flange assemblies, pressure vessels, and structural connections where high-strength fastening is required.

This stud and nut package is suited for use in industrial, commercial, and heavy-duty mechanical applications. ASTM A193 Grade B7 alloy steel studs are widely used in flanged pipe connections, heat exchangers, pumps, valves, and pressure equipment operating under elevated temperature or high-stress conditions. Each package includes four studs and eight nuts, providing complete bolt-up hardware for typical flange work. No additional nuts need to be sourced separately.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength fastening
• Fully threaded along the entire 7.25-inch length for maximum engagement flexibility
• 1-1/8-8 thread size with 7B class of fit for standard allowance assembly
• Uncoated finish suitable for service where coatings are not required or permitted
• Package includes four studs and eight nuts for complete bolt-up hardware

Compatibility

Designed as an OEM-style replacement or new-installation fastener for flanged assemblies, pressure vessels, and structural connections requiring ASTM A193 Grade B7 alloy steel studs with a 1-1/8-8 thread specification.

Installation Notes

Installation is typically performed by licensed pipefitters or millwrights in accordance with applicable ASME or plant maintenance standards. Ensure all mating flanges and equipment are depressurized and de-energized before removing or installing fasteners. Thread engagement should be verified and studs should be installed hand-tight before applying final torque in a cross-pattern sequence per the applicable flange specification. Do not reuse studs that show thread damage, stretching, or corrosion.
