Value Collection B7SN0630325CP Threaded Stud Nut 5/8-11

Product Description

The VALUE COLLECTION B7SN0630325CP is a fully threaded stud and nut assembly used in high-strength fastening applications across mechanical, industrial, and trade service work. Each stud measures 5/8-11 thread size and 3.25 inches in length, manufactured from Grade B7 alloy steel in an uncoated finish. The 7B class of fit ensures consistent thread engagement and reliable torque transfer. This package includes four studs and eight nuts, making it suitable for multi-point flange connections, equipment mounting, and structural fastening jobs where ASTM A193 compliance is required.

This stud and nut set is suited for piping flanges, pressure vessel assemblies, heat exchangers, and general mechanical fastening in both residential and commercial settings. The Grade B7 designation meets ASTM A193 standards, making these studs appropriate for elevated temperature and pressure service. Plumbers, pipefitters, millwrights, and mechanical contractors commonly install these in bolted flange joints and equipment tie-down applications.

Installation Notes

Installation is performed by pipefitters, millwrights, or licensed plumbers following applicable ASME and ASTM guidelines for bolted flange joints. De-energize and depressurize the system fully before disassembling any flanged connection. Apply a suitable thread lubricant or anti-seize compound to stud threads before assembly to prevent galling and ensure accurate torque readings. Follow the applicable flange standard for proper bolt tightening sequence.
