Value Collection MSCC704700 Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION MSCC704700 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, industrial, and construction assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The screw measures 1-8 thread size by 1-1/2 inches in length under head, following Unified National Coarse (UNC) thread standards. It meets ASME B18.2.1 and SAE J429 specifications, making it suitable for demanding bolted joint applications where material traceability and dimensional consistency are required.

This hex head cap screw is used in general industrial maintenance, OEM equipment assembly, structural fastening, and heavy-duty mechanical installations. Its Grade 8 rating makes it appropriate for applications requiring high clamp load and shear strength, including automotive, agricultural equipment, and machinery frames. Full threading along the shank length allows engagement across the entire fastener length, which is useful in shorter-grip fastening scenarios or when threading into a tapped hole without a nut.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Fully threaded shank for maximum thread engagement
• UNC thread standard ensures broad compatibility with standard hex nuts and tapped holes
• Meets ASME B18.2.1 and SAE J429 dimensional and material standards
• 1-8 thread size by 1-1/2 inches length under head

Compatibility

Designed as a standard UNC hex head cap screw compatible with 1-8 threaded hex nuts, washers, and tapped holes conforming to ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or mechanical contractors using a standard hex wrench or impact driver sized to the fastener head. Always verify the mating thread and nut grade are appropriate for the joint design before installation. De-energize or lock out any equipment before replacing fasteners on machinery per OSHA lockout/tagout procedures. Do not mix Grade 8 fasteners with lower-grade nuts or hardware, as mismatched grades compromise joint integrity.
