Value Collection R52001082 Machine Screw 1/4-20 X 5 in

Product Description

The VALUE COLLECTION R52001082 is a 1/4-20 flat head Phillips machine screw manufactured from steel with a zinc-plated finish. It measures 5 inches in overall length and is designed for use in threaded fastening applications across mechanical assembly, equipment mounting, and structural fabrication work. The flat head profile sits flush with or below the mating surface when fully driven into a countersunk hole. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light industrial environments. This screw conforms to ASME B18.6.3 and SAE J82 standards, making it appropriate for applications requiring documented dimensional and material compliance.

This screw is suited for general mechanical assembly tasks where a flush or countersunk finish is required. Common applications include equipment panels, enclosures, mounting brackets, and structural components. The 1/4-20 thread size is a widely used coarse-thread configuration in North American inch-standard hardware. Installers in HVAC, electrical, plumbing, and light fabrication trades routinely use this fastener size for control panel assembly, equipment support structures, and field modifications to manufactured equipment.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard inch-system tapped holes
• Flat head profile provides a flush or countersunk finish in mating surfaces
• Phillips drive for use with standard Phillips screwdrivers and bit drivers
• Zinc-plated steel construction for general indoor and light-duty corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material grade standards
• 5-inch overall length accommodates thicker material stacks or deep fastening applications

Compatibility

Designed as an inch-standard replacement fastener for any application requiring a 1/4-20 flat head Phillips machine screw with a 5-inch overall length and zinc-plated steel finish.

Installation Notes

Ensure the mating material has a properly sized and tapped 1/4-20 through-hole or blind hole before installation. Use a matching Phillips bit driver or screwdriver to prevent cam-out and head damage. When installing into countersunk applications, verify the countersink angle matches the flat head angle to achieve proper seating. Power down or de-energize any equipment before driving fasteners into electrical enclosures or live panels.
