Value Collection MPFI02500370-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPFI02500370-100BX is a 1/4-20 UNC flat head Phillips drive machine screw used in general mechanical assembly and fastening applications. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw features a 3/8-inch overall length and a countersunk flat head profile that sits flush with the mating surface when properly installed. Sold in a box of 100, it is a standard fastener stocked by maintenance technicians, electricians, HVAC installers, and general trade professionals who need reliable threaded fasteners in volume.

This screw is suited for light-to-medium duty fastening in sheet metal, electrical enclosures, equipment panels, junction boxes, and structural assemblies where a flush head is required. The 1/4-20 UNC thread pitch is one of the most common coarse-thread sizes in inch-standard mechanical work, making this fastener a routine fit for replacement or new-installation tasks across HVAC, electrical, and general trade applications. The zinc finish provides baseline protection in dry to mildly humid environments.

Key Features

• Flat countersunk head sits flush with the surface for a clean, low-profile finish
• Phillips drive compatible with standard screwdrivers and power drivers
• 1/4-20 UNC coarse thread — widely used inch-standard thread size
• Grade 2 steel construction for general-purpose fastening duty
• Zinc finish provides basic corrosion protection in dry environments
• Box of 100 units supports volume installation and maintenance work

Compatibility

Designed as a general-purpose inch-standard machine screw for use in applications requiring a 1/4-20 UNC coarse-thread flat head fastener with Phillips drive.

Installation Notes

Install using a Phillips screwdriver or power driver with a properly sized bit to avoid cam-out and head damage. Ensure the receiving material is tapped or fitted with a compatible 1/4-20 nut or threaded insert before driving. Do not over-torque, as Grade 2 steel has lower proof load ratings than higher-grade fasteners. Follow applicable codes and equipment manufacturer guidelines for fastener specifications in regulated installations.
