Value Collection B7SN0500250CP Threaded Stud Nut 1/2-13

Product Description

The VALUE COLLECTION B7SN0500250CP is a fully threaded stud with nut, engineered for high-strength fastening applications where consistent clamping force and corrosion resistance are required. The stud is manufactured from alloy steel to Material Grade B7 specifications per ASTM A193, making it well suited for elevated-temperature and high-pressure bolting. The 1/2-13 thread size with a 7B class of fit ensures proper engagement and reliable torque transfer. Each package includes four studs and eight nuts, supplied uncoated. Licensed tradespeople and industrial maintenance technicians typically select this fastener for demanding mechanical assemblies.

This fully threaded stud is commonly used in industrial piping flanges, pressure vessel assemblies, HVAC equipment mounting, and structural mechanical connections. The Grade B7 alloy steel construction makes it appropriate for service environments involving elevated temperatures or cyclic loading. Each stud measures 2-1/2 inches in length with a 1/2-13 thread, fitting standard hex nuts and flange nuts of the corresponding thread specification. Installation is typically performed by millwrights, pipefitters, or mechanical technicians working to ASME or ASTM fastener standards.

Key Features

Compatibility

Designed as a standard replacement or stock fastener for applications requiring 1/2-13 fully threaded Grade B7 studs with nuts, including industrial flanges, mechanical equipment frames, and pressure-rated assemblies conforming to ASTM A193 specifications.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or mechanical technician familiar with ASTM fastener standards. Always de-energize, depressurize, and isolate any system before replacing or installing fasteners on pressurized or energized equipment. Inspect threads for damage before installation and apply an appropriate thread lubricant or anti-seize compound as required by the application. Do not mix Grade B7 studs with lower-grade nuts in high-pressure or high-temperature service.
