Value Collection MSC65160160-1 Hex Cap Screw 7/8-9 Grade 8

Product Description

The VALUE COLLECTION MSC65160160-1 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers elevated tensile strength and corrosion resistance compared to lower-grade alternatives. The 7/8-9 UNC thread size and 3-3/4 inch length under head make it well suited for heavy-duty bolted connections where clamp load and fatigue resistance are critical. It conforms to ASME B18.2.1 and SAE J429 standards, ensuring dimensional and mechanical property compliance for demanding applications.

This cap screw is commonly used in heavy equipment assembly, agricultural machinery, structural steel connections, and industrial fabrication. The partial threading allows for a smooth shank bearing surface in the joint grip area, which is preferred in applications where shear loading is present or where precise clamping across thick material stacks is required. Machinists, maintenance technicians, millwrights, and general industrial assemblers routinely install this type of fastener.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for critical bolted joints
• Zinc yellow dichromate finish offers corrosion resistance and is visually identifiable as a Grade 8 fastener
• Partially threaded shank accommodates shear loads and precise grip-length clamping
• 7/8-9 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Meets ASME B18.2.1 dimensional standards and SAE J429 mechanical property requirements
• 3-3/4 inch length under head suits thick-section assemblies and heavy structural connections

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/8-9 UNC nuts, washers, and tapped holes in industrial and structural fastening applications.

Installation Notes

Installation is performed with a standard 1-3/8 inch hex wrench or socket. Torque to the value specified by the joint designer or applicable engineering standard for Grade 8 fasteners at this diameter. Always ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not reuse fasteners that show signs of galling, thread damage, or deformation.
