Value Collection B7SN0500400CP Threaded Stud Nut 1/2-13 4in

Product Description

The VALUE COLLECTION B7SN0500400CP is a fully threaded stud with nuts, designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. Each stud is manufactured from steel to ASTM A193 material standards at a Grade B7 material rating, delivering reliable tensile strength for bolted connections under elevated stress or temperature conditions. The thread size is 1/2-13 (1/2 inch diameter, 13 threads per inch, UNC) with a 7B class of fit, and each stud measures 4 inches in overall length. This package includes 4 studs and 8 nuts. Installers in plumbing, mechanical, and structural trades commonly use Grade B7 all-thread studs for flange assemblies, equipment mounting, and pressure vessel connections.

Grade B7 fully threaded studs are a standard fastener choice in industrial piping systems, pressure equipment flanges, and structural bolting applications. The 1/2-13 thread size is widely used across residential and commercial mechanical systems. These studs are suitable for use where ASTM A193 B7 material compliance is required, such as pipe flange bolting per ASME B16.5 or similar standards. The uncoated finish makes them compatible with a range of field-applied coatings or lubricants as needed for the installation environment.

Key Features

• Grade B7 steel construction meets ASTM A193 material standard for high-strength fastening
• 1/2-13 thread size with 7B class of fit for consistent thread engagement
• 4 inches overall length suits standard flange and mechanical assembly depths
• Fully threaded along the entire length for flexible engagement positioning
• Uncoated finish compatible with field-applied lubricants or anti-seize compounds
• Package includes 4 studs and 8 nuts for complete assembly sets

Compatibility

Designed as a standard ASTM A193 Grade B7 fully threaded stud for use in industrial piping, flange bolting, and mechanical equipment applications requiring 1/2-13 UNC thread fasteners.

Installation Notes

Installation should be performed by a qualified mechanical or pipefitting trade professional familiar with bolted flange procedures. De-energize or depressurize any system before servicing fasteners on pressure-bearing equipment. Apply a compatible anti-seize or thread lubricant as required by the service environment and applicable codes such as ASME PCC-1 for pressure boundary joints. Do not mix Grade B7 studs with incompatible nut grades; use ASTM A194 Grade 2H heavy hex nuts for code-compliant flange assemblies where specified.
