Value Collection MPFI02502250-100BX Flat Head Machine Screw

Product Description

The VALUE COLLECTION MPFI02502250-100BX is a 1/4-20 x 2-1/4-inch flat head Phillips machine screw designed for general-purpose fastening in metal and other rigid materials. Built to ASME Grade 2 standards, this screw features a zinc-plated steel construction that provides corrosion resistance in typical indoor and light industrial environments. The flat head profile sits flush with the mating surface when fully driven, making it well suited for applications where a low-profile finish is required. This box contains 100 screws, making it appropriate for contractors, maintenance technicians, and fabricators who need reliable fasteners in volume.

This screw is commonly used in light structural assembly, electrical panel work, HVAC equipment mounting, general mechanical fabrication, and maintenance repair operations. The Unified National Coarse (UNC) thread form on the 1/4-20 designation is the most widely used thread standard in North American trade work, compatible with standard tapped holes, hex nuts, and coupling nuts of the same thread specification. The Phillips drive allows installation with standard Phillips screwdrivers or power bits.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and fastener hardware
• 2-1/4-inch overall length with full-length thread under head
• Flat head profile seats flush for clean, low-profile installations
• Phillips drive compatible with standard hand and power tools
• Zinc-plated finish provides corrosion resistance in dry to light-moisture environments
• Grade 2 steel construction meets general-purpose mechanical strength requirements

Compatibility

Designed as a general-purpose 1/4-20 UNC machine screw suitable for use with any standard 1/4-20 tapped hole, nut, or threaded insert in metal, plastic, or composite assemblies where Grade 2 strength meets the application requirement.

Installation Notes

Installation requires a Phillips screwdriver or bit sized for a number 3 Phillips drive, appropriate to this screw diameter. Always verify the mating hole is properly tapped to 1/4-20 UNC before driving to avoid cross-threading. Do not overtighten Grade 2 fasteners in thin or soft base materials. Follow applicable mechanical codes and torque guidelines for the specific assembly being fastened.
