Value Collection B7SN0630350CP Threaded Stud Nut 5/8-11

Product Description

The VALUE COLLECTION B7SN0630350CP is a fully threaded stud with nuts, manufactured from alloy steel to ASTM A193 Grade B7 specifications. Each stud measures 3.5 inches in length with a 5/8-11 UNC thread size and a 7B class of fit. The uncoated finish leaves the base steel surface exposed, which is common for high-strength fastener applications where post-installation coating or specific torque requirements govern the assembly. This package includes four studs and eight nuts, making it suitable for bolted flange connections, pressure vessel assemblies, pipe flanges, and structural mechanical joints serviced by pipefitters, millwrights, and maintenance technicians.

These Grade B7 threaded studs are used in industrial and commercial applications requiring high tensile strength fasteners. Common installation scenarios include flanged pipe connections, heat exchanger assemblies, pump housings, and equipment mounting in HVAC, plumbing, and process piping systems. The 5/8-11 thread size is a standard coarse-thread designation widely used across trade and industrial fastener specifications. Each package contains four studs and eight nuts, providing double-nut coverage per stud for standard bolted joint configurations.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength bolted joint applications
• 5/8-11 UNC coarse thread with 7B class of fit for consistent thread engagement
• 3.5-inch fully threaded length provides maximum engagement flexibility across varying joint thicknesses
• Uncoated finish suitable for assemblies where additional coating or lubrication is applied in the field
• Package includes four studs and eight nuts for complete double-nut installation

Compatibility

Designed as a standard-duty replacement or maintenance fastener for flanged connections, pressure vessel joints, and mechanical assemblies requiring 5/8-11 UNC Grade B7 threaded studs per ASTM A193 specifications.

Installation Notes

Installation is typically performed by pipefitters, millwrights, or maintenance mechanics working on flanged pressure systems. Always de-energize, depressurize, and isolate the system before replacing fasteners on active piping or equipment. Thread engagement, lubrication, and torque requirements should follow the applicable flange standard or engineering specification for the assembly. Refer to ASME B16.5 or the relevant piping code for torque and gasket seating requirements when used in pressure-rated flange applications.
