Value Collection B7SN1000450CP Threaded Stud Nut Grade B7

Product Description

The VALUE COLLECTION B7SN1000450CP is a fully threaded stud and nut assembly manufactured from Grade B7 alloy steel with an uncoated finish. Each stud measures 1-8 thread size and 4.5 inches in length, conforming to ASTM A193 standards for high-strength fastener applications. The 7B class of fit ensures consistent thread engagement and reliable clamping force in demanding service conditions. This assembly is installed by mechanical contractors, pipefitters, and industrial maintenance technicians working on bolted flange connections, pressure vessels, and structural assemblies where tensile strength and thread integrity are critical.

This stud and nut package is suited for use in industrial, commercial, and heavy mechanical applications where ASTM A193 Grade B7 hardware is specified. Typical installations include pipe flange bolting, heat exchanger assemblies, pressure vessel closures, and structural bolted connections. The 7B thread fit class is compatible with standard heavy hex nut configurations. Each package contains 4 studs and 8 nuts, providing complete hardware for multiple connection points on a single flange or assembly.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 specification for high-strength stud bolts
• 1-8 thread size with 7B class of fit for consistent thread engagement
• 4.5-inch length suits standard flange and pressure vessel bolting applications
• Uncoated finish suitable for applications where additional coatings are applied in the field or not required
• Each package includes 4 studs and 8 nuts for complete flange bolt sets

Compatibility

Designed as an OEM-style replacement or new-installation fastener for bolted flange and pressure vessel connections requiring ASTM A193 Grade B7 fully threaded stud hardware with 1-8 thread size.

Installation Notes

Installation of threaded studs and nuts on pressurized systems should be performed by qualified pipefitters or mechanical technicians following applicable codes including ASME B31.3 and relevant flange assembly standards. De-energize, depressurize, and isolate any system before removing or replacing flange hardware. Use calibrated torque tooling to achieve specified flange bolt load per the applicable joint assembly procedure. Inspect thread condition on mating components before installation to ensure proper fit and full thread engagement.
