Value Collection 402072PR Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 402072PR is a partially threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and light industrial applications. It features a 5/16-18 UNC thread size and measures 3-1/2 inches under the head. Manufactured from Grade 2 steel with a bright uncoated finish, this fastener is suited for indoor or protected-environment assemblies where corrosion resistance is not a primary requirement. Installation is performed with a standard hex wrench or socket driver. This screw ships in a minimum order quantity of 50 pieces.

This hex head cap screw is used in a wide range of trade and maintenance applications including equipment mounting, brackets, HVAC component assemblies, and general mechanical fabrication. The partial thread design provides a smooth unthreaded shank section under the head, which is useful when clamping two materials together and a bearing surface is needed between the fastened parts. It is compatible with standard 5/16-18 UNC threaded nuts and tapped holes across inch-measurement hardware.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-series hardware
• 3-1/2 inch length under head with partial threading for clamping applications
• Grade 2 steel construction suitable for general-purpose fastening
• Bright uncoated finish — no added coating that could affect dimensional fit in tight tolerances
• Hex drive head accepts standard socket or open-end wrench tooling

Compatibility

Designed for use with standard 5/16-18 UNC threaded nuts, washers, and tapped holes in inch-measurement fastener applications.

Installation Notes

Installation is typically performed by a maintenance technician or journeyman mechanic using a standard 1/2-inch hex socket or open-end wrench. Always ensure the mating thread is clean and free of debris before installation. Do not exceed the torque rating appropriate for Grade 2 steel fasteners as specified by your application engineering standards. Avoid use in outdoor or high-moisture environments without additional corrosion protection, as the uncoated finish offers no rust resistance.
