Value Collection 86853371 Hex Cap Screw 3/8-16 X 1 in Grade 8

Product Description

The VALUE COLLECTION 86853371 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc-plated finish for corrosion resistance, this fastener features a 3/8-16 UNC thread and a 1-inch length under head. The hex drive format accommodates standard wrenches and sockets for fast, reliable installation. Grade 8 classification indicates a minimum proof load well above that of common hardware-grade fasteners, making it appropriate for demanding load-bearing connections. Sold in packages of 10.

This screw is suited for use in equipment assembly, machinery repair, automotive applications, and general structural fastening where high tensile strength is required. The UNC thread form is the standard inch-series coarse thread, compatible with standard 3/8-16 nuts, inserts, and tapped holes. The fully threaded body provides maximum thread engagement across the full 1-inch length, which is advantageous in thinner material stacks or where grip length flexibility is needed.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc-plated finish provides corrosion protection in light-duty environments
• Fully threaded body maximizes thread engagement along the entire shank
• 3/8-16 UNC thread form fits standard inch-series nuts and tapped holes
• Hex head drive accepts standard wrenches and impact sockets
• Packaged in quantities of 10 for jobsite or shop use

Compatibility

Designed for use with standard 3/8-16 UNC nuts, hex nuts, lock nuts, flat washers, and tapped holes machined to UNC thread standards. Compatible with Grade 8 or equivalent-rated fastener hardware in inch-series fastener assemblies.

Installation Notes

Installation is performed with a standard hex wrench, combination wrench, or socket set sized for a 3/8-16 fastener. Always ensure the mating nut or tapped hole is clean and free of debris before threading. Apply torque per the applicable engineering specification for Grade 8 fasteners at this thread size — do not exceed rated torque for the joint material. Zinc plating is not rated for high-temperature or heavily corrosive environments; evaluate finish suitability before use in such conditions.
