Value Collection D39175 Hex Head Cap Screw 3/4-10 Grade 8

Product Description

The VALUE COLLECTION D39175 is a partially threaded hex head cap screw designed for high-strength fastening applications in structural and mechanical 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 carries a 3/4-10 UNC thread size with a 2-3/4 inch length under head, conforming to ASME B18.2.1 dimensional standards. The hex drive configuration accepts standard hex wrenches and impact sockets, making it a reliable choice for production and maintenance environments.

This screw is suited for heavy-duty mechanical and structural installations where Grade 8 tensile requirements apply, including equipment mounting, machinery frames, and structural steel connections. The partial thread design provides a smooth shank section that improves shear load performance and allows for controlled clamping force in bolted joint assemblies. It is commonly specified by millwrights, maintenance mechanics, and construction trades working with inch-series fastener standards.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance and visual grade identification
• Partially threaded shank improves shear resistance in bolted joints
• 3/4-10 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 for dimensional consistency

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts and tapped holes conforming to inch-series thread standards in heavy-duty mechanical and structural fastening applications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with bolted joint specifications. Always verify that mating nut or tapped hole thread class is compatible with 3/4-10 UNC before assembly. Use a calibrated torque wrench and apply the appropriate torque specification per the equipment manufacturer or applicable engineering standard. Inspect the zinc dichromate finish for damage before installation, as coating integrity affects corrosion performance.
