Value Collection C703086 Hex Head Cap Screw 5/16-18 X 5 in

Product Description

The VALUE COLLECTION C703086 is a Grade 8 steel hex head cap screw with a 5/16-18 UNC thread pattern and a 5-inch length under head. It is partially threaded and left uncoated, making it suited for high-strength fastening applications where a bare steel finish is acceptable. Grade 8 designation indicates a high-tensile-strength fastener capable of handling demanding load requirements. This screw meets ASME B18.2.1 dimensional standards, ensuring consistent head geometry and thread tolerances. Electricians, HVAC technicians, plumbers, and general tradespeople reach for Grade 8 hex cap screws when standard fasteners are not strong enough for the application.

This fastener is used in mechanical assemblies, equipment mounting, structural bracketing, and trade installations where high-strength bolting is required. The 5/16-18 thread size is common in light-to-medium industrial and trade applications. The partial threading allows the unthreaded shank to bear shear loads more effectively than a fully threaded fastener. Sold in a package quantity of 25, this screw is practical for both single-job use and small-stock replenishment on a service truck or shop bench.

Key Features

• Grade 8 steel construction for high tensile strength in demanding fastening applications
• 5/16-18 UNC thread pattern for broad compatibility with standard inch-system hardware
• 5-inch length under head with partial threading to support shear load on the shank
• Uncoated finish — suitable where coating is not required or where field coating will be applied
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Packaged in quantities of 25 for efficient jobsite or shop use

Compatibility

Designed as a standard inch-system hex head cap screw for use with any 5/16-18 UNC-tapped hole or compatible nut in trade, mechanical, or equipment-mounting applications.

Installation Notes

Install using an appropriately sized hex wrench or socket driver. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Do not mix inch and metric hardware — confirm thread engagement before applying torque. Inspect threads for damage before installation and replace any fastener that shows signs of corrosion or deformation.
