Value Collection D39476 Hex Head Cap Screw 3/4-16 X 3 in

Product Description

The VALUE COLLECTION D39476 is a partially threaded hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength and corrosion resistance. Built to Grade 8 steel specifications, this fastener delivers the clamping force needed for demanding mechanical and structural assemblies. The 3/4-16 UNF thread profile provides fine thread engagement for precise torque control, while the zinc yellow dichromate finish offers baseline protection against oxidation. At 3 inches in length under the head, this screw suits medium-depth fastening tasks across a range of industrial and mechanical installations. Compliance with ASME B18.2.1 ensures dimensional consistency across the production run.

This cap screw is suited for use in mechanical assemblies, equipment mounting, and structural connections where Grade 8 strength is required. Partial threading allows the unthreaded shank to bear shear loads, making it appropriate for pivot points, clevis connections, and close-tolerance bolt holes. Typical installers include industrial mechanics, millwrights, and maintenance technicians working on machinery, fabricated steel structures, and heavy equipment. The 3/4-16 fine thread specification is common in applications where vibration resistance and precise preload control are priorities.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/4-16 UNF fine thread for improved vibration resistance and torque accuracy
• Partially threaded shank to carry shear loads in close-tolerance applications
• Zinc yellow dichromate finish for corrosion protection in general-duty environments
• Meets ASME B18.2.1 dimensional standards for consistent fitment
• Inch measurement system for compatibility with standard UNF tooling and hardware

Compatibility

Designed as a standard 3/4-16 UNF hex head cap screw for use with any Grade 8-rated nut or tapped hole conforming to ASME B18.2.1 dimensional requirements in inch-series fastener applications.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a calibrated torque wrench sized for 3/4-inch hex fasteners. Verify that mating threads and tapped holes are clean, undamaged, and free of debris before assembly. Always apply the specified torque value from the equipment manufacturer or applicable engineering standard for Grade 8 fasteners of this thread size. De-energize and lock out any equipment before servicing fastened assemblies on powered machinery.
