Value Collection 402056PR 5/16-18x1 Hex Cap Screw Grade 2

Product Description

The VALUE COLLECTION 402056PR is a fully threaded hex head cap screw sized 5/16-18 x 1 inch, manufactured from Grade 2 steel with a bright, uncoated finish. This standard fastener is designed for general-purpose bolting applications where high-strength alloy grades are not required. The 5/16-18 designation indicates a 5/16-inch nominal diameter with 18 threads per inch on a Unified National Coarse (UNC) thread form. Full threading along the 1-inch length under head provides maximum thread engagement across the fastener's entire shank, making it well suited for thin-material assemblies and through-bolting situations.

This cap screw is commonly used in light-duty mechanical assemblies, equipment frames, electrical enclosures, HVAC sheet metal work, and general trade maintenance tasks. Its UNC thread form is compatible with standard 5/16-18 nuts and tapped holes found throughout residential and commercial equipment. The bright uncoated finish is appropriate for indoor or protected applications where corrosion exposure is minimal. This item is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• 5/16-18 UNC thread form for compatibility with standard nuts and tapped holes
• Fully threaded shank provides maximum thread engagement over the full 1-inch length under head
• Grade 2 steel construction suitable for general-purpose, light-duty fastening
• Bright uncoated finish for clean, bare-metal appearance in protected environments
• Hex head drive style accepts standard hex wrenches and sockets
• Inch measurement system with length measured under head per industry standard

Compatibility

Designed for use with any standard 5/16-18 UNC threaded nut, insert, or tapped hole in general mechanical and trade assembly applications.

Installation Notes

Installation requires a standard hex wrench or socket sized for a 5/16-inch hex head cap screw. Always ensure the mating thread (nut or tapped hole) is the same 5/16-18 UNC specification before driving the fastener. Do not apply power tools at high torque settings without a torque specification from the equipment manufacturer, as Grade 2 steel has lower proof load limits than Grade 5 or Grade 8 fasteners. Follow applicable mechanical codes and equipment service documentation for proper fastener selection and installation procedure.
