Value Collection R50000172 Machine Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION R50000172 is a 1/4-20 UNC flat head Phillips machine screw designed for general-purpose fastening in metal, wood, and composite assemblies. At 3/4 inches overall length with a flat head profile, this screw sits flush with or below the mating surface when installed in a countersunk hole. Constructed from Grade 2 steel with a zinc plating, it provides adequate corrosion resistance for indoor and light-duty applications. The Phillips drive allows fast installation with standard hand or power tools. This screw ships in a minimum order quantity of 100 units per package.

This fastener is suited for light- to medium-duty mechanical assemblies where a flush or countersunk finish is required. Typical applications include equipment enclosures, electrical panels, HVAC cabinet assemblies, and general sheet metal or structural fastening. The 1/4-20 UNC thread form is one of the most common coarse-thread inch-series sizes, making replacement hardware easy to source. It is installed by electricians, HVAC technicians, plumbers, and general maintenance professionals across residential and commercial jobsites.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Flat head profile seats flush when installed in a properly countersunk hole

Compatibility

Designed as a general-purpose 1/4-20 UNC machine screw suitable for use anywhere a flat head Phillips fastener of this thread size and length is specified.

Installation Notes

Install using a No. 2 Phillips screwdriver or bit driver. The mating surface should be countersunk to the correct angle to allow the flat head to seat flush. De-energize any electrical equipment and follow applicable NEC or OSHA lockout/tagout procedures before replacing fasteners in live panels or enclosures. Do not overtighten, as Grade 2 steel has lower proof load ratings than Grade 5 or Grade 8 fasteners.
