Value Collection R50000176 Flat Head Phillips Screw 1/4-20

Product Description

The VALUE COLLECTION R50000176 is a 1/4-20 x 1-3/4 inch flat head Phillips machine screw manufactured from Grade 2 steel with a zinc-plated finish. It features a unified national coarse (UNC) thread form and is measured by overall length at 1-3/4 inches. The flat head profile sits flush with the mating surface when installed into a countersunk hole, making it a standard fastener choice for sheet metal assemblies, electrical enclosures, equipment panels, and general mechanical fabrication. This fastener is installed by electricians, HVAC technicians, plumbers, and general maintenance trades wherever a flush-mount, Phillips-drive machine screw is required.

This screw is suited for light-duty to medium-duty applications in residential and commercial settings. Typical uses include securing control panel covers, junction box lids, equipment brackets, and structural components where a 1/4-20 UNC thread pitch is specified. The zinc plating provides baseline corrosion resistance appropriate for indoor and protected-outdoor installations. This item is sold in a minimum order quantity of 100 pieces per order.

Key Features

• 1/4-20 UNC thread form for compatibility with standard tapped holes and hex nuts
• Flat head design countersinks flush with the mating surface for clean panel installations
• Phillips drive for use with standard Phillips screwdrivers and bits
• Grade 2 steel construction provides adequate tensile strength for general-purpose fastening
• Zinc-plated finish offers corrosion resistance in dry and lightly humid environments
• No washer — overall length and length under head are equal at 1-3/4 inches

Compatibility

Designed as a general-purpose 1/4-20 UNC flat head Phillips machine screw suitable for use wherever that thread size and head style are specified in equipment assembly, panel work, or structural fastening applications.

Installation Notes

Install using a properly sized Phillips screwdriver or bit to avoid cam-out and head damage. When threading into tapped holes, ensure the thread engagement depth meets the requirements of the applicable assembly specification. Power down and de-energize any electrical equipment before fastening or removing panel hardware in live electrical or control enclosures. Follow applicable NEC or equipment manufacturer guidelines for fastener reuse and torque requirements.
