Value Collection D30005 Hex Head Cap Screw 1/4-20 X 1-1/4 in

Product Description

The VALUE COLLECTION D30005 is a hex head cap screw intended for general mechanical assembly and fastening applications across trade and industrial settings. It features a 1/4-20 UNC thread with a 1-1/4 inch length under head and is partially threaded, meaning the shank includes an unthreaded grip section. The fastener is manufactured from Grade 5 steel with a zinc-plated finish for basic corrosion resistance. It conforms to ASME B18.2.1 dimensional standards, making it a direct fit for applications that call out to that specification. Plumbers, HVAC technicians, electricians, and general maintenance crews regularly use this screw size for equipment panel attachment, bracket mounting, and mechanical component assembly.

This screw is suited for light-to-medium duty fastening in residential and commercial trade applications. Common install scenarios include securing electrical enclosure covers, HVAC equipment brackets, plumbing support hardware, and similar structural connections where a standard 1/4-20 UNC thread pattern is specified. The partial threading provides a bearing shank for applications requiring shear load resistance or precise clamping across unthreaded material layers.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard tapped holes and nuts
• 1-1/4 inch length under head accommodates moderate material stack-up
• Partially threaded shank provides shear resistance and controlled clamp load
• Grade 5 steel construction meets medium-strength fastener requirements
• Zinc-plated finish provides baseline corrosion protection in dry or mildly humid environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw per ASME B18.2.1, compatible with any tapped hole or nut rated for a 1/4-20 UNC thread pattern in steel or compatible material assemblies.

Installation Notes

Install using a properly sized hex wrench or socket driver; standard drive size for 1/4-20 hex head cap screws is 7/16 inch across flats. Ensure mating threads are clean and free of debris before installation. Do not overtighten into tapped blind holes in soft materials such as aluminum without appropriate torque guidance from the equipment manufacturer. Zinc-plated fasteners are not rated for outdoor or high-humidity continuous exposure without additional protective measures.
