Value Collection B7SN0500300CP Threaded Stud Nut 1/2-13

Product Description

The VALUE COLLECTION B7SN0500300CP is a fully threaded stud and nut fastener set designed for high-strength bolted connections in industrial and mechanical applications. Each stud measures 1/2-13 thread size and 3 inches in overall length, manufactured from Grade B7 alloy steel to meet ASTM A193 standards. The uncoated finish suits applications where plating or coating is either unnecessary or specified separately. This package includes four studs and eight nuts, making it a ready-to-install set for bolted flange, pipe, or equipment assemblies. Millwrights, pipefitters, and maintenance technicians working on pressure vessels, flanges, and structural connections commonly use this fastener type.

Grade B7 threaded studs are a standard choice in industrial piping systems, pressure vessel assembly, heat exchangers, and heavy equipment mounting. The 7B thread fit class provides the clearance tolerance appropriate for general industrial assembly while maintaining reliable clamping load. These studs are commonly installed in environments where elevated mechanical strength is required and where ASTM A193 Grade B7 is called out in engineering specifications. The pack-of-four quantity suits small repair jobs, field service kits, and maintenance stock.

Key Features

• 1/2-13 thread size with 3-inch overall length for standard industrial bolted connections
• Grade B7 alloy steel construction meets ASTM A193 specification for high-strength fasteners
• 7B thread fit class provides proper clearance tolerance for general industrial assembly
• Uncoated finish for use where bare steel or field-applied coatings are required
• Each package includes four studs and eight nuts for complete ready-to-install sets

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for industrial bolted assemblies requiring ASTM A193 Grade B7 fully threaded studs with 1/2-13 thread form.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or mechanical technician following applicable codes and engineering specifications. De-energize and depressurize the assembly completely before removing or replacing fasteners in pressurized systems. Use calibrated torque equipment to achieve the specified clamp load — do not substitute hand-tight estimates on pressure-rated connections. Follow ASME or applicable flange assembly standards for stud installation sequence and lubrication requirements.
