Value Collection 97030 Hex Head Cap Screw 5/16-18 Grade 5

Product Description

The VALUE COLLECTION 97030 is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and trade assembly applications. It carries a 5/16-18 UNC thread profile and measures 1-1/4 inches under the head. Manufactured from Grade 5 steel with no coating applied, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1. Sold in a 100-piece package, it is well suited for jobsite stock, service van inventory, and production assembly where consistent fastener supply is required.

This screw is applicable across a wide range of trade installations including HVAC equipment mounting, plumbing support bracketing, electrical enclosure assembly, and general mechanical fabrication. The UNC thread form is the standard inch-series coarse thread, compatible with tapped holes and standard hex nuts in that size. The uncoated finish makes it appropriate for dry or controlled indoor environments. Installers working in corrosive or outdoor environments should evaluate whether an additional corrosion-resistant finish is required for the specific application.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes and fastener hardware
• 1-1/4 inch length under head for medium-depth fastening in structural and mechanical connections
• Grade 5 steel construction meets ASME B18.2.1 mechanical requirements
• Fully threaded shank provides consistent thread engagement along the entire fastener length
• Uncoated finish suitable for dry indoor assembly and general-purpose use
• 100-piece packaging supports bulk stocking and repeat-use applications

Compatibility

Designed as a standard inch-series hex head cap screw for use with 5/16-18 UNC tapped holes, standard hex nuts, and flat or lock washers conforming to ASME inch fastener standards.

Installation Notes

Installation requires a standard hex wrench or socket in the appropriate size for a 5/16 hex head cap screw. Ensure mating threads are clean and free of debris before installation. Torque to values appropriate for Grade 5 fasteners per the applicable mechanical or structural specification governing the installation. Follow NEC, IFGC, IPC, or other applicable trade codes when using fasteners in code-governed assemblies.
