Value Collection D39091 Hex Head Cap Screw 7/16-14 X 4 in

Product Description

The VALUE COLLECTION D39091 is a partially threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers high tensile strength and corrosion resistance suited for demanding service environments. The 7/16-14 UNC thread size and 4-inch length under head make it a common choice for bolted assemblies where precise clamping force and thread engagement are required. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fitment across standard tooling and hardware. Installed using a standard hex wrench or socket, this screw is a staple in industrial, mechanical, and construction trades.

This cap screw is appropriate for use in general industrial machinery, structural steel connections, heavy equipment maintenance, and fabrication work. The partial threading provides a smooth shank section that resists shear forces and allows accurate alignment of mating components before full thread engagement. It is commonly specified by millwrights, maintenance mechanics, and general contractors working on bolted steel assemblies that require a high-strength UNC fastener meeting recognized dimensional standards.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance in moderate exposure environments
• Partial threading allows shank to bear shear loads and aid component alignment
• 7/16-14 UNC thread form for broad compatibility with standard nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standard for consistent, interchangeable fitment
• Hex head drive accepts standard sockets, wrenches, and impact tooling

Compatibility

Designed as a standard replacement or stock fastener for applications requiring a 7/16-14 UNC partially threaded hex head cap screw in Grade 8 steel meeting ASME B18.2.1 specifications.

Installation Notes

Installation is performed using a standard hex socket or open-end wrench sized for a 7/16-14 hex head fastener. Always verify the mating nut or tapped hole thread class and condition before assembly. Torque to the value specified by the equipment manufacturer or applicable structural design specification for Grade 8 fasteners. Avoid reusing fasteners that show signs of thread damage, corrosion, or deformation.
