Value Collection MPRI02502000-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPRI02502000-100BX is a 1/4-20 UNC machine screw designed for general-purpose fastening in metal, wood, and fabricated assemblies. It features a round head profile with a Phillips drive, allowing installation with standard Phillips screwdrivers or power drivers. The screw measures 2 inches in length under the head and is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance in dry indoor applications. This fastener ships in a box of 100 pieces, making it practical for production assembly, MRO restocking, and field repair kits used by electricians, HVAC technicians, and general contractors.

This screw is suited for light- to medium-duty fastening tasks in residential and commercial construction, equipment assembly, and panel work. The 1/4-20 UNC thread is one of the most common inch-series thread forms in North American trade applications, compatible with standard 1/4-20 nuts, threaded inserts, and tapped holes. The round head sits above the work surface and distributes clamping load over a broad bearing area, making it appropriate for through-hole applications where a low-profile flat head is not required. No washer is included or required under the head for standard installations.

Key Features

• 1/4-20 UNC thread form — standard inch-series coarse thread for broad hardware compatibility
• 2-inch length under head for sufficient grip in typical through-bolt and tapped-hole applications
• Round head with Phillips drive — installs with common #2 Phillips screwdrivers or bit drivers
• Grade 2 steel construction provides adequate strength for light- to medium-duty fastening
• Zinc finish for basic corrosion resistance in dry, indoor environments
• Box quantity of 100 pieces supports production runs, stocking, and multi-unit service calls

Compatibility

Designed for use with standard 1/4-20 UNC tapped holes, hex nuts, and threaded inserts in inch-series fastener applications across general construction, electrical, HVAC, and mechanical assembly work.

Installation Notes

Install with a #2 Phillips screwdriver or a power driver fitted with a #2 Phillips bit. Ensure the mating hole or nut matches the 1/4-20 UNC thread specification before driving to avoid cross-threading. For electrical panel or equipment enclosure work, follow applicable NEC guidelines regarding fastener type and torque requirements as specified by the equipment manufacturer. The zinc finish is intended for dry indoor use; select a stainless or coated alternative for wet or outdoor environments.
