Value Collection MPFI02500500-050B Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPFI02500500-050B is a 1/4-20 UNC flat head Phillips machine screw designed for general fastening applications across a wide range of trade and industrial uses. The screw measures 1/2 inch in overall length and is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance for indoor and light-duty environments. The flat head profile sits flush with or below the mating surface when countersunk, making it well suited for panels, brackets, and assemblies where a low-profile fastener is required. This package contains 50 pieces, sized and threaded for use with standard 1/4-20 tapped holes or nuts.

This machine screw is appropriate for residential and light commercial applications where a 1/4-20 UNC thread pattern is specified. Common install scenarios include electrical panel brackets, HVAC equipment mounting plates, plumbing fixture brackets, and general equipment assembly. The Phillips drive allows installation with standard hand tools or power drivers. The zinc finish is suitable for dry or low-humidity interior environments. Sold in a quantity of 50 per order.

Installation Notes

Install using a Phillips head screwdriver or Phillips bit with a power driver sized for a 1/4-20 fastener. Always de-energize electrical equipment before installing or removing fasteners on or near energized components. Use a properly sized countersink when a flush mount is required for the flat head profile. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners.
