Value Collection 3120CHAL Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 3120CHAL is a hex head cap screw designed for fastening applications that require a lightweight, corrosion-resistant metal fastener. Manufactured from 2024T4 aluminum, this screw features a 5/16-18 thread size on a Unified National Coarse (UNC) thread standard and measures 1-1/4 inches in length under the head. The 1/2-inch hex drive is compatible with standard wrenches and sockets. This screw is suited for use in environments where steel fasteners are too heavy or prone to corrosion, making it a practical choice for HVAC panels, aluminum enclosures, and similar light-duty structural or sheet-metal assemblies installed by mechanical and electrical trade professionals.

This cap screw is intended for use in inch-system assemblies calling for a 5/16-18 UNC thread pattern. Typical applications include securing aluminum framework, equipment panels, junction box covers, and access doors in light commercial and residential installations. The 2024T4 alloy offers good strength relative to its weight, making it appropriate for moderate-load fastening tasks where aluminum-to-aluminum or aluminum-to-composite connections are required.

Key Features

• 2024T4 aluminum construction provides a balance of strength and corrosion resistance without the weight of steel
• 5/16-18 UNC thread pattern for compatibility with standard inch-system tapped holes and nuts
• 1-1/4 inches length under head for moderate material stack-up applications
• 1/2-inch hex drive accepts standard wrenches and sockets for straightforward installation
• Lightweight profile reduces overall assembly weight in panels and enclosures

Compatibility

Designed as a standard inch-system hex head cap screw for use in any assembly calling for a 5/16-18 UNC thread, 1-1/4-inch grip length, and an aluminum fastener material.

Installation Notes

Installation is performed by mechanical or electrical tradespeople using a 1/2-inch open-end wrench, combination wrench, or socket driver. De-energize and lock out any electrical equipment before accessing panels or enclosures. Avoid overtightening aluminum fasteners, as the alloy is softer than steel and susceptible to thread stripping under excessive torque. Follow applicable codes and equipment manufacturer guidelines for fastener torque and material compatibility.
