Value Collection 49162 Hex Head Cap Screw Grade B7 Steel

Product Description

The VALUE COLLECTION 49162 is a heavy-duty hex head cap screw engineered for high-strength bolting applications. Manufactured from Grade B7 alloy steel to ASTM A193 standards, this fastener is designed for use in high-temperature and high-pressure environments where structural integrity is critical. The 1-1/4-7 UNC thread size and 5-inch length under head make it suitable for demanding industrial and mechanical assemblies. The uncoated finish is standard for applications where a separate coating, plating, or lubricant will be applied by the installer. Maintenance technicians, pipefitters, and industrial mechanics are the primary trades handling this fastener class.

This screw is used in flanged pipe connections, pressure vessel assemblies, industrial machinery, and structural bolting applications. ASTM A193 Grade B7 fasteners are a recognized standard in petrochemical, power generation, and heavy industrial environments where elevated temperature and high-stress loading conditions are present. The UNC thread form ensures broad compatibility with standard inch-series nuts and tapped holes. Sold in packages of 5, this SKU is appropriate for both maintenance stock and job-specific procurement.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 specification for high-strength bolting
• 1-1/4-7 UNC thread form for compatibility with standard inch-series hardware
• 5-inch length under head suits deep-flange and thick-plate assemblies
• Uncoated finish ready for field-applied coatings, lubricants, or anti-seize compounds
• Sold in a package of 5 fasteners per order unit

Compatibility

Designed as an ASTM A193 Grade B7 hex head cap screw for use with standard 1-1/4-7 UNC inch-series nuts and tapped components in industrial bolting applications.

Installation Notes

Installation should be performed by qualified pipefitters, millwrights, or mechanical technicians following applicable industry standards such as ASME PCC-1 for pressure boundary bolted flange joints. De-energize and depressurize the system fully before disassembling any flanged or bolted connection. Apply anti-seize or specified lubricant to threads before torquing unless the job specification requires dry installation. Always verify torque requirements from the applicable engineering specification or flange standard before tightening.
