Value Collection 3124CHAL Hex Head Cap Screw 5/16 18

Product Description

The VALUE COLLECTION 3124CHAL is a hex head cap screw machined from 2024T4 aluminum, sized at 5/16-18 x 1-1/2 inches with a 1/2-inch hex drive. It is a standard UNC-threaded fastener used across mechanical assembly, structural, and equipment applications where a lightweight, corrosion-resistant fastener is required. The 2024T4 aluminum grade offers a strong strength-to-weight ratio compared to mild steel fasteners, making it a practical choice in aerospace, automotive, and general fabrication work where weight savings matter. Installation requires a standard hex socket or open-end wrench.

This cap screw is suited for use in light-to-medium duty fastening applications across residential and commercial equipment, machinery frames, enclosures, and fabricated assemblies. The 5/16-18 UNC thread pattern is one of the most common inch-series thread sizes, making this screw widely compatible with standard tapped holes and hex nuts of the same specification. It is sold individually, with a minimum order quantity of 10 units per purchase.

Key Features

• 2024T4 aluminum construction provides high strength-to-weight ratio for weight-sensitive assemblies
• 5/16-18 UNC thread standard ensures compatibility with standard inch-series tapped holes and nuts
• 1-1/2 inches length under head suits medium-depth fastening applications
• 1/2-inch hex drive accepts standard sockets and open-end wrenches
• Aluminum material offers natural corrosion resistance without additional coating

Compatibility

Designed for use in any application requiring a 5/16-18 UNC hex head cap screw in 2024T4 aluminum. Fits standard inch-series tapped holes and hex nuts of the same thread specification.

Installation Notes

Installation is performed by machinists, fabricators, maintenance technicians, and general tradespeople. Always ensure the mating thread is clean and free of debris before installation. Aluminum fasteners are susceptible to galling under high torque — apply an appropriate anti-seize compound when threading into aluminum or steel tapped holes. Do not exceed manufacturer-rated torque for the alloy grade to avoid thread stripping or fastener failure.
