Value Collection 1428CHAL Hex Head Cap Screw 1/4-20 Aluminum

Product Description

The VALUE COLLECTION 1428CHAL is a hex head cap screw machined from 2024T4 aluminum alloy. It features a 1/4-20 UNC thread profile and measures 1-3/4 inches in length under the head. The 7/16-inch hex drive accepts standard hex wrenches and sockets for installation. 2024T4 aluminum provides a strong, lightweight fastener suitable for applications where steel weight is a concern and corrosion exposure is limited. This screw is used by machinists, millwrights, electricians, and general contractors working with aluminum structures, enclosures, or equipment frames.

This fastener is suited for light- to medium-duty structural and mechanical assembly applications where aluminum compatibility is required. Typical installations include aluminum framing, electrical enclosures, HVAC equipment panels, and similar fabricated assemblies. The UNC thread form is the standard coarse-thread series used across most inch-system mechanical and structural applications in North America. Sold individually, with a minimum order quantity of 100 pieces per order.

Key Features

• 2024T4 aluminum alloy construction — lightweight with good tensile strength
• 1/4-20 UNC coarse thread — widely compatible with standard inch-system tapped holes
• 1-3/4 inch length under head for moderate grip-length requirements
• 7/16-inch hex drive accepts common wrenches and sockets
• Aluminum material reduces galvanic corrosion risk when mating with aluminum components

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 1/4-20 UNC hex head cap screw in 2024T4 aluminum at 1-3/4 inches length under head.

Installation Notes

Install using a 7/16-inch hex wrench or socket driver. Power down or de-energize any equipment before fastening into electrical enclosures or panels. Aluminum fasteners are softer than steel — avoid over-torquing, which can strip threads or shear the head. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
