Value Collection B7SN1000475CP Threaded Stud Nut 1-8 Steel

Product Description

The VALUE COLLECTION B7SN1000475CP is a fully threaded stud with nuts, manufactured from Grade B7 alloy steel with an uncoated finish. Each stud measures 4.75 inches in length with a 1-8 thread size and a 7B class of fit, making it suitable for high-strength bolted connections in industrial and mechanical applications. This package includes four studs and eight nuts. Compliance with ASTM A193 ensures the fasteners meet established material and mechanical property standards commonly specified in pressure vessel, piping, and structural assemblies. Licensed tradespeople and maintenance professionals install these in environments where reliable clamping force and dimensional consistency are required.

These threaded studs are used in industrial piping systems, flanged connections, pressure vessel assemblies, and heavy mechanical equipment where ASTM A193 Grade B7 fasteners are called out by specification. The 7B thread fit class indicates a unified external thread tolerance suitable for applications requiring controlled thread engagement. The package quantity of four studs with two nuts per stud supports standard double-nut installation configurations common in flange bolting work.

Compatibility

Designed as an OEM-style replacement or maintenance fastener for industrial flanged connections, pressure vessels, and mechanical assemblies specifying ASTM A193 Grade B7 fully threaded studs with a 1-8 thread and 7B class of fit.

Installation Notes

Installation of threaded studs in flanged or pressure-rated assemblies should be performed by qualified mechanical or pipefitting tradespeople following applicable codes such as ASME B16.5 and ASME PCC-1 for bolted joint assembly. Shut down and depressurize the system completely before removing or replacing fasteners in any pressurized application. Inspect threads on both the stud and mating component before installation, and ensure proper lubrication per the governing engineering specification. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.
