Value Collection D30025 Hex Head Cap Screw 5/16-18 X 1/2 in

Product Description

The VALUE COLLECTION D30025 is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and trade assembly applications. It features a 5/16-18 UNC thread size with a 1/2-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish for basic corrosion resistance. Conforming to ASME B18.2.1 standards, this fastener delivers consistent dimensional tolerances and reliable clamping force. It is used by HVAC technicians, electricians, plumbers, and general tradespeople for equipment mounting, panel assembly, and structural connections where a medium-strength steel fastener is required.

This hex head cap screw is suited for light to medium-duty fastening tasks in both residential and commercial trade applications. Common uses include securing equipment brackets, junction boxes, access panels, pipe hangers, and sheet metal assemblies. The fully threaded shank allows full thread engagement across the grip length, making it appropriate for thinner material applications where partial threading would reduce holding strength. The zinc-plated finish provides adequate protection in dry indoor environments.

Key Features

• 5/16-18 UNC thread size with 1/2-inch length under head for compact fastening applications
• Grade 5 steel construction provides medium-strength clamping suitable for general trade use
• Fully threaded shank allows maximum thread engagement in thin-material assemblies
• Zinc-plated finish offers basic corrosion resistance for indoor installations
• Conforms to ASME B18.2.1 for consistent dimensional accuracy and interchangeability
• Inch measurement system with UNC thread standard for compatibility with standard SAE tooling

Compatibility

Designed as a standard inch-series hex head cap screw conforming to ASME B18.2.1, suitable for use wherever a 5/16-18 UNC fully threaded fastener is specified in equipment assembly or structural connection applications.

Installation Notes

Install with a standard 1/2-inch wrench or socket driver appropriate for a 5/16-18 hex head fastener. De-energize and lock out all electrical or mechanical systems before fastening components in live equipment. Do not exceed the design load capacity of Grade 5 steel fasteners in critical structural applications. Follow applicable codes including NEC, IPC, or IFGC as relevant to the trade application when securing system components.
