Value Collection B7SN1250500UP Threaded Stud Nut B7 Steel 4pk

Product Description

The VALUE COLLECTION B7SN1250500UP is a fully threaded stud and nut assembly designed for high-strength bolted connections in industrial and mechanical applications. Each stud features a 1-1/4-8 thread size, measures 5 inches in overall length, and is manufactured to ASTM Grade B7 specification, which indicates alloy steel with high tensile strength suited for demanding service conditions. The uncoated finish means no plating or coating has been applied, which is standard for many industrial flange and structural applications where field coating or direct contact with a mating surface is preferred. Each package includes four studs and eight nuts.

This stud and nut set is typically used in flange bolting, pressure vessel assembly, structural connections, and general industrial fastening where Grade B7 alloy steel is called out by specification. The 7B thread fit class provides a standard internal thread tolerance appropriate for nuts used with B7 threaded rod stock. This type of fastener is commonly installed by pipefitters, millwrights, and maintenance mechanics working on pressure equipment, pumps, valves, and structural steel.

Key Features

• Grade B7 alloy steel construction for high-tensile-strength bolting applications
• 1-1/4-8 thread size with 7B class of fit for consistent nut engagement
• 5 inches overall length suits standard flange and structural bolt patterns
• Uncoated finish suitable for field coating or direct torque-to-yield applications
• Each package includes four studs and eight nuts for complete assembly

Compatibility

Designed as a Grade B7 fully threaded stud and nut assembly conforming to standard 1-1/4-8 UNC thread specifications for use in industrial flange, pressure vessel, and structural bolting applications where ASTM A193 Grade B7 fasteners are specified.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical technician following applicable codes such as ASME B16.5 for flanged connections or the applicable pressure equipment standard. Depressurize and isolate any system before removing or replacing fasteners. Apply the specified lubricant or anti-seize compound to threads as required by the joint specification, and use a calibrated torque wrench to achieve the required bolt load. Do not mix Grade B7 studs with lower-grade nuts in pressure-rated assemblies.
