Value Collection D39169-1 Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION D39169-1 is a fully 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 superior tensile strength and corrosion resistance compared to lower-grade hardware. It measures 3/4-10 thread size with a 1-1/4 inch length under head, conforming to ASME B18.2.1 standards. The UNC thread form ensures broad compatibility with standard inch-series tapped holes and nuts. Machinists, millwrights, and maintenance technicians rely on this grade for demanding bolted joint applications where fastener integrity is critical.

This cap screw is suited for use in heavy equipment assembly, industrial machinery, structural steel connections, and general mechanical fabrication where Grade 8 strength is specified. The fully threaded shank provides maximum thread engagement across the full clamping length, making it appropriate for shorter grip-length applications where partial threading would reduce holding capacity. The zinc yellow dichromate finish offers mild corrosion protection in indoor and sheltered environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance and visual grade identification
• Fully threaded shank maximizes thread engagement over the full 1-1/4 inch length
• 3/4-10 UNC thread conforms to ASME B18.2.1 inch-series standard
• Hex head drive accepts standard 1-1/8 inch hex wrenches and impact sockets

Compatibility

Designed for use with standard 3/4-10 UNC inch-series nuts, washers, and tapped holes conforming to ASME and UNC thread specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using calibrated torque wrenches sized for 3/4-inch hex fasteners. Always degrease mating surfaces and inspect threads for damage before assembly. Do not mix Grade 8 fasteners with lower-grade nuts or tapped holes not rated for the corresponding load. Follow applicable industry or equipment manufacturer torque specifications for the joint being assembled.
