Value Collection D39084 Hex Head Cap Screw 7/16-14

Product Description

The VALUE COLLECTION D39084 is a 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 alternatives. It features a 7/16-14 UNC thread size, a length under head of 2.25 inches, and partial threading along the shank. Compliance with ASME B18.2.1 ensures dimensional consistency and interchangeability across standard hex cap screw applications. Machinists, millwrights, and maintenance technicians are the primary installers.

This screw is suited for use in heavy-duty bolted connections where Grade 8 strength is specified, such as machinery frames, structural brackets, automotive components, and equipment assemblies. The partial thread design allows the unthreaded shank to bear shear loads, making it appropriate for joints where shear strength is a design consideration. The zinc yellow dichromate finish provides a moderate level of corrosion protection for indoor and sheltered outdoor environments.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Zinc yellow dichromate finish provides corrosion resistance and is visually identifiable as Grade 8
• 7/16-14 UNC thread size for broad compatibility with standard inch-series nuts and tapped holes
• Partial threading allows the shank to carry shear loads in bolted joints
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/16-14 UNC nuts, threaded inserts, and tapped holes in Grade 8 or equivalent high-strength fastener applications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using standard hex wrenches or socket drive tools. Always verify that the mating nut, insert, or tapped hole is rated for Grade 8 fastener loads before assembly. Torque to the value specified in the applicable engineering drawing or fastener torque table for 7/16-14 Grade 8 fasteners. Do not mix Grade 8 fasteners with lower-grade nuts, as the mating hardware must match the strength grade to achieve the intended clamp load.
