Value Collection D39085 Hex Cap Screw 7/16-14 X 2.5 in Grade 8

Product Description

The VALUE COLLECTION D39085 is a partially threaded hex head cap screw engineered for high-strength fastening applications. Manufactured from Grade 8 steel, it delivers a minimum tensile strength appropriate for demanding structural and mechanical assemblies. The screw features a 7/16-14 UNC thread form, measures 2.5 inches under the head, and is finished with a zinc yellow dichromate coating that provides corrosion resistance and is visually distinguishable from lower-grade fasteners. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fitment with standard hex tooling and hardware.

This fastener is suited for industrial, mechanical, and structural applications where high-clamping-force hardware is required. Partial threading is standard for this length, allowing the unthreaded shank to bear shear loads in bolted joint assemblies. Typical users include millwrights, maintenance technicians, and mechanical contractors working on equipment frames, machinery mounts, and structural steel connections. This screw ships in a single-piece package quantity with a minimum order of 10 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 7/16-14 UNC thread for broad compatibility with standard nuts and tapped holes
• Partially threaded shank to handle shear loads in bolted assemblies
• Zinc yellow dichromate finish provides corrosion resistance and grade identification
• Conforms to ASME B18.2.1 dimensional standards
• 2.5 inch length under head suits medium-depth clamping applications

Compatibility

Designed as a standard 7/16-14 UNC hex head cap screw compatible with any 7/16-14 hex nut, coupling nut, or tapped hole meeting ASME B18.2.1 specifications.

Installation Notes

Installation is performed with a standard 5/8 inch hex wrench or socket driver. Torque to the fastener joint's engineered specification for Grade 8 hardware per applicable mechanical or structural codes. Ensure mating threads are clean and free of debris before installation. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware reduces joint integrity.
