Value Collection B7HHB075C500 Hex Head Cap Screw

Product Description

The VALUE COLLECTION B7HHB075C500 is a 3/4-10 x 5-inch hex head cap screw manufactured from Grade B7 alloy steel with an uncoated finish. Grade B7 designates a chromium-molybdenum alloy steel known for high tensile strength and resistance to elevated temperatures, making it a standard choice in industrial fastening applications. The fastener features a unified coarse thread (UNC) pitch of 10 threads per inch, a hex drive head, and a 5-inch length under the head. Plumbers, pipefitters, millwrights, and general industrial mechanics install this type of fastener in structural, flange, and pressure-equipment assemblies where high-strength bolting is required.

This hex head cap screw is suited for use in industrial and commercial applications where ASTM A193 Grade B7 specification fasteners are called for. Typical installation scenarios include pipe flange bolting, pressure vessel assembly, pump and compressor mounting, and structural steel connections. The uncoated finish is appropriate for applications where a secondary coating, plating, or lubricant will be applied by the installer, or where bare alloy steel is acceptable per the assembly specification.

Key Features

• Grade B7 chromium-molybdenum alloy steel for high tensile strength and elevated-temperature service
• 3/4-10 UNC thread — coarse pitch for reliable engagement in standard tapped holes and nuts
• 5-inch length under head suits deep flange and structural bolting applications
• Uncoated finish allows field application of lubricants, anti-seize, or coatings per job spec
• Inch measurement system — compatible with standard UNC hardware

Compatibility

Designed as an OEM-style replacement or direct-install fastener for industrial and commercial assemblies requiring 3/4-10 UNC Grade B7 hex head cap screws per ASTM A193 or equivalent specifications.

Installation Notes

Installation is performed by licensed pipefitters, millwrights, or qualified mechanical technicians following applicable codes such as ASME PCC-1 for pressure boundary bolted flange joints. De-energize and depressurize any connected system before fastener removal or installation. Use a calibrated torque wrench and apply fastener lubricant or anti-seize compound as specified by the joint design engineer. Do not mix Grade B7 fasteners with lower-grade hardware in the same flange assembly.
