Value Collection D39214 Hex Head Cap Screw 1-8x2 Grade 8

Product Description

The VALUE COLLECTION D39214 is a fully threaded hex head cap screw designed for high-strength fastening applications in demanding trade and industrial environments. 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 2 inches in length under head, following Unified National Coarse (UNC) thread standards. It meets ASME B18.2.1 dimensional requirements, making it a dependable choice for structural and mechanical assemblies. Licensed tradespeople and maintenance professionals specify this grade when joint integrity and load-bearing reliability are priorities.

This cap screw is suited for heavy-duty bolted connections in mechanical, structural, and equipment-mounting applications. Its full threading along the 2-inch shank provides maximum thread engagement, which is critical in through-bolted assemblies or applications requiring nuts seated at varying positions along the fastener. Typical use cases include machinery frames, equipment brackets, HVAC unit mounting, and general structural steel connections where a high-strength UNC fastener is called for. The zinc yellow dichromate finish provides a measurable layer of corrosion protection for both indoor and moderate outdoor service environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank maximizes thread engagement across the full 2-inch length
• Zinc yellow dichromate finish provides corrosion resistance and is visually identifiable as Grade 8
• UNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability
• Hex head drive accepts standard open-end, box, and socket wrenches

Compatibility

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

Installation Notes

Installation is performed by qualified mechanical or maintenance tradespeople using standard hex wrenches or impact sockets rated for the fastener size. Always inspect mating threads and hardware for damage or contamination before assembly. Follow applicable torque tables for Grade 8 UNC fasteners as specified by the equipment manufacturer or relevant industry standards. Do not mix Grade 8 fasteners with lower-grade nuts or mismatched thread standards, as this can compromise joint integrity.
