Value Collection 5040CHAL Hex Head Cap Screw 1/2-13 Aluminum

Product Description

The VALUE COLLECTION 5040CHAL is a hex head cap screw machined from 2024T4 aluminum, designed for structural fastening applications where corrosion resistance and reduced weight matter. The screw features a 1/2-13 UNC thread size with a length under head of 2.5 inches, and a 3/4-inch hex drive. The 2024T4 aluminum alloy offers good tensile strength relative to its weight, making it a common choice in aerospace, mechanical, and fabrication work. This screw is sold in multiples of 5.

This cap screw is suited for use in assemblies requiring a lightweight fastener with standard UNC inch threading. Typical applications include aluminum structural frames, mechanical enclosures, custom fabrications, and equipment where steel fasteners would add unnecessary weight or create galvanic compatibility concerns with aluminum mating components. It is installed using a standard 3/4-inch hex wrench or socket.

Key Features

• 2024T4 aluminum alloy construction for lightweight, moderate-strength fastening
• 1/2-13 UNC thread for compatibility with standard inch-system tapped holes
• 2.5-inch length under head for adequate thread engagement in thicker assemblies
• 3/4-inch hex head drive accepts standard wrenches and sockets
• Sold in multiples of 5 to support job-lot procurement

Compatibility

Designed as a standard inch-system hex head cap screw for use in any application requiring a 1/2-13 UNC threaded fastener in 2024T4 aluminum.

Installation Notes

Install using a 3/4-inch hex wrench, combination wrench, or socket driver. De-energize or depressurize any system before replacing or adding fasteners in live assemblies. When torquing aluminum fasteners, avoid overtightening, as aluminum threads can strip or gall under excessive load. Consult applicable mechanical or structural codes for torque requirements specific to your application.
