Value Collection MPRI02501750-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPRI02501750-100BX is a 1/4-20 x 1-3/4-inch round head Phillips machine screw manufactured from Grade 2 steel with a zinc-plated finish. Sold in a box of 100, this fastener is sized for general-purpose mechanical assembly where a standard UNC thread pattern and corrosion-resistant coating are required. The round head profile provides a low-profile, finished appearance on exposed surfaces. The zinc plating offers basic protection against oxidation in dry and mildly humid environments. Length is measured from under the head.

This screw is suited for light to medium-duty assembly applications across residential, commercial, and light industrial settings. Common uses include panel assembly, enclosure fabrication, equipment mounting, and general mechanical fastening where a 1/4-20 UNC thread is specified. The Phillips drive is compatible with standard power drivers and manual screwdrivers, making it practical for high-volume assembly work on the bench or in the field.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 1-3/4-inch length measured from under the head
• Round head profile for a clean finished appearance on exposed surfaces
• Phillips drive accepts standard bits for manual and power installation
• Grade 2 steel construction provides adequate strength for general-purpose fastening
• Zinc-plated finish offers basic corrosion resistance in dry to mildly humid conditions

Compatibility

Designed as a general-purpose replacement or stock fastener for any application requiring a 1/4-20 UNC round head Phillips machine screw measuring 1-3/4 inches in length under head.

Installation Notes

Install using a Phillips-tip screwdriver or power driver with the appropriate bit size to avoid cam-out and head damage. Always verify the mating thread is 1/4-20 UNC before driving to prevent cross-threading. De-energize any electrical enclosure or equipment before fastening panels or covers. Avoid over-torquing Grade 2 fasteners, as they have lower proof strength than higher-grade hardware.
