Value Collection MPFI02500500-100BX Machine Screw 100pk

Product Description

The VALUE COLLECTION MPFI02500500-100BX is a 1/4-20 UNC machine screw with a flat head and Phillips drive, supplied in a box of 100. Manufactured from Grade 2 steel with a zinc-plated finish, these fasteners are suited for general-purpose mechanical assembly where a flush or countersunk seating surface is required. The overall length is 1/2 inch, measured from the tip to the top of the head, with a length under head also measuring 1/2 inch, confirming full-thread engagement across the entire shank. The zinc plating provides baseline corrosion resistance for indoor and light-duty applications.

These screws are used across a wide range of trade and light industrial assembly tasks, including electrical panel mounting, equipment enclosure assembly, HVAC cabinet fabrication, and general sheet metal or machined-part fastening. The 1/4-20 UNC thread is one of the most common unified coarse thread standards in North American trade work, making these a practical shop or service-van consumable. The flat head profile allows the fastener to sit flush or below the surface in countersunk holes, which is important in applications where protruding fastener heads would interfere with fit or clearance.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hardware
• Flat head profile seats flush in countersunk holes, eliminating surface protrusion
• Phillips drive for use with standard screwdrivers and power bits
• Grade 2 steel construction provides adequate strength for general-purpose fastening
• Zinc-plated finish adds corrosion resistance for indoor and light-duty environments
• Sold in a 100-count box for jobsite or shop stock replenishment

Compatibility

Designed for general-purpose use in any application requiring a 1/4-20 UNC flat head Phillips machine screw with a 1/2-inch overall length and countersunk hole clearance.

Installation Notes

Install using a Phillips No. 2 screwdriver or bit rated for the drive size. Ensure the mating hole is properly tapped or threaded to 1/4-20 UNC specification and countersunk to the appropriate angle to accept the flat head profile. De-energize any electrical equipment before fastening hardware to live assemblies. Do not overtighten, as Grade 2 fasteners have lower proof-load ratings than higher-grade hardware.
