Value Collection -40623-6B Threaded Stud 1-1/8-8 8in Steel B7

Product Description

The VALUE COLLECTION -40623-6B is a fully threaded stud machined from Grade B7 alloy steel. It carries a 1-1/8-8 thread profile (1-1/8 inch nominal diameter, 8 threads per inch) and measures 8 inches in overall length. The uncoated finish leaves the base material exposed, which is standard for high-strength fastener applications where plating is not required or where field coating will be applied. Grade B7 material meets ASTM A193 requirements, making it suitable for high-temperature and high-pressure bolting in industrial and mechanical systems. Threaded full length, it gives the installer maximum engagement flexibility on both ends without a plain shank section.

This stud is used in flanged joint assemblies, pressure vessel connections, pipe flange bolting, and heavy mechanical equipment mounting where ASTM A193 Grade B7 specification is required. It is commonly installed in industrial piping systems, pumping equipment, heat exchangers, and structural fastening applications that demand controlled tensile and yield strength. The 7B thread fit class provides a standard external thread tolerance suitable for use with 7H or 7G class nuts. It is installed by millwrights, pipefitters, industrial mechanics, and maintenance technicians working to ASME or plant-specific bolting procedures.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 specification for high-strength bolting
• 1-1/8-8 thread form with 7B external thread fit class for standard nut engagement
• Fully threaded along the entire 8-inch length for flexible installation depth
• Uncoated finish suitable for applications requiring bare steel or field-applied coating
• Sold in packages of 25 with a minimum order quantity of 1 package

Compatibility

Designed for use in flanged joint and pressure vessel bolting applications requiring ASTM A193 Grade B7 fully threaded studs with a 1-1/8-8 thread form and 8-inch length.

Installation Notes

Installation is performed by qualified pipefitters, millwrights, or mechanical technicians following applicable ASME flange bolting procedures and plant torque specifications. Always verify nut thread class compatibility with the 7B external thread before assembly. Apply thread lubricant or anti-seize compound per the applicable bolting specification to achieve accurate clamp load. Inspect threads for damage prior to installation and do not use studs with deformed or galled thread profiles.
