Value Collection B7SN0630725CP Threaded Stud Nut 5/8-11 B7

Product Description

The VALUE COLLECTION B7SN0630725CP is a fully threaded stud with nuts, manufactured from Grade B7 alloy steel and sold in a pack of four studs with eight nuts. The stud measures 5/8-11 thread size and 7.25 inches in length. It carries an uncoated finish and meets the ASTM A193 standard, making it suitable for high-strength bolting applications in mechanical and industrial assemblies. The 7B class of fit designates an external thread tolerance class appropriate for heavy hex nuts and structural connections. Licensed trades and industrial maintenance technicians working on pressure vessels, flanges, pipe assemblies, and structural equipment commonly specify this configuration.

This stud-and-nut assembly is used in applications that require high-strength, fully threaded fasteners. The ASTM A193 Grade B7 designation covers alloy steel studs intended for use in high-temperature or high-pressure flanged joints, heat exchangers, pressure vessels, and piping systems. The 5/8-11 thread pitch is a standard coarse thread suitable for pairing with heavy hex nuts across a wide range of industrial and mechanical installations. Each package contains four studs and eight nuts, providing a complete fastener set per application point.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 requirements for high-strength bolting
• 5/8-11 coarse thread size with 7B external thread fit class for reliable engagement with heavy hex nuts
• Fully threaded 7.25-inch length allows flexible installation depth and nut positioning
• Uncoated finish suitable for use with thread sealants, lubricants, or coatings applied in the field
• Package includes four studs and eight nuts for complete assembly

Compatibility

Designed as a standard ASTM A193 Grade B7 fully threaded stud for use in high-strength bolting applications including flanged pipe joints, pressure vessel closures, and structural mechanical assemblies requiring 5/8-11 coarse thread fasteners.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or maintenance mechanic familiar with ASTM A193 fastener specifications and applicable codes such as ASME B31.3 for process piping or ASME Section VIII for pressure vessels. Depressurize and de-energize the assembly before replacing studs. Verify thread engagement length and apply appropriate thread lubricant or anti-seize compound as required by the service specification. Do not exceed the torque values specified by the equipment manufacturer or the applicable code document for the fastener grade and size.
