Value Collection 39079 Hex Head Cap Screw 7/16-14 X 1 in Grade 8

Product Description

The VALUE COLLECTION 39079 is a fully threaded hex head cap screw designed for high-strength fastening applications across mechanical, structural, and industrial assembly work. Built to Grade 8 steel specification, this fastener delivers the elevated tensile and proof-load strength required in demanding environments where standard Grade 5 hardware is insufficient. The 7/16-14 thread designation indicates a 7/16-inch nominal diameter with 14 threads per inch on a UNC (Unified National Coarse) thread form. Overall length under head measures 1 inch. A zinc yellow dichromate finish provides corrosion resistance suitable for general indoor and moderate-exposure outdoor use. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This cap screw is suited for bolted connections in manufacturing equipment, heavy machinery, automotive assemblies, agricultural implements, and structural fabrications where Grade 8 performance is specified. The UNC thread form ensures broad compatibility with standard hex nuts, lock nuts, and threaded plate inserts. The fully threaded shank allows clamping load to be applied across the full grip length, making it appropriate for thin-material stack-ups and close-tolerance assemblies. Sold in a pack of 50 units, this fastener is practical for production runs, shop stock replenishment, and maintenance inventory.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Fully threaded shank for maximum thread engagement across the full grip length
• 7/16-14 UNC thread form for compatibility with standard inch-series hardware
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• Pack quantity of 50 units supports shop stock and production use

Compatibility

Designed for use with standard 7/16-14 UNC hex nuts, flat washers, lock washers, and threaded inserts conforming to inch-series fastener standards.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using a properly sized hex wrench or socket. Always verify that mating threads are clean and free of debris before assembly. Consult applicable engineering or equipment specifications for required torque values, as proper preload is critical for Grade 8 fastener performance. Use thread-locking compounds or mechanical locking hardware only where specified by the assembly design.
