Value Collection D39174 Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION D39174 is a fully threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener offers strong corrosion resistance alongside the elevated tensile strength that Grade 8 classification provides. The 3/4-10 UNC thread and 2.5-inch length under head make it suitable for heavy-duty structural and mechanical assemblies. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fit across standard tooling and hardware. Maintenance technicians, millwrights, and industrial contractors commonly specify this grade for applications requiring reliable clamping force under dynamic or high-load conditions.

This cap screw is suited for use in industrial machinery, structural steel connections, heavy equipment fabrication, and general mechanical assemblies where Grade 8 strength and UNC threading are required. The fully threaded shank allows engagement along the entire bolt length, making it well-matched to through-bolt configurations and close-tolerance tapped holes. It is sold individually with a minimum order quantity of 10 units, appropriate for maintenance stock or small-batch fabrication needs.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding fastening applications
• Zinc yellow dichromate finish delivers corrosion resistance in industrial and outdoor environments
• Fully threaded shank allows maximum thread engagement along the entire 2.5-inch length
• 3/4-10 UNC thread form is compatible with standard hex nuts, locknuts, and tapped steel components
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment with standard tooling

Compatibility

Designed as a standard 3/4-10 UNC hex head cap screw per ASME B18.2.1, compatible with any application specifying a Grade 8 steel fully threaded hex cap screw in that thread size and length.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench sized for 3/4-inch hex fasteners. Follow the engineer-specified or OEM torque values for the application, as Grade 8 fasteners require higher torque than lower-grade equivalents. Inspect threads on both the bolt and mating nut or tapped hole before installation to prevent galling. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.
