Value Collection MPRI02502500-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPRI02502500-100BX is a 1/4-20 round head Phillips machine screw designed for general fastening applications in mechanical assemblies, equipment fabrication, and structural component attachment. Manufactured from Grade 2 steel with a zinc finish, this screw measures 2.5 inches in length under the head and uses Unified National Coarse (UNC) threading. It is sold in a box of 100 pieces. Installers working in HVAC equipment, electrical enclosures, and light structural assemblies will find this a reliable general-purpose fastener for standard inch-series applications.

This screw is suited for residential and commercial maintenance, repair, and assembly tasks where a 1/4-20 UNC thread form is specified. The round head profile provides a low-profile dome finish above the mating surface, and the Phillips drive allows use with common power or hand drivers. Grade 2 steel construction meets standard requirements for general-purpose mechanical fastening where higher-grade alloy is not required. Box quantity of 100 units supports job-site and shop stock needs.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes
• 2.5-inch length under head for adequate thread engagement in thicker assemblies
• Round head profile with Phillips drive for fast installation using standard drivers
• Grade 2 steel construction for general-purpose mechanical fastening duty
• Zinc finish provides basic corrosion resistance for indoor and protected applications
• Box of 100 pieces supports shop stock and multi-unit service work

Compatibility

Designed as a general-purpose inch-series machine screw for use in any application requiring a 1/4-20 UNC round head Phillips fastener with a 2.5-inch length under head.

Installation Notes

Installation is performed with a Phillips head screwdriver or compatible power driver bit. Ensure the receiving hole is properly tapped to 1/4-20 UNC before driving to avoid thread damage. Do not overtorque, as Grade 2 steel has lower proof load ratings than Grade 5 or Grade 8 fasteners. Follow applicable equipment manufacturer specifications and relevant codes when used in electrical or mechanical enclosures.
