Value Collection MPRI02501250-100BX Machine Screw 100pk

Product Description

The VALUE COLLECTION MPRI02501250-100BX is a 1/4-20 UNC machine screw in a round head, Phillips drive configuration. Made from Grade 2 steel with a zinc-plated finish, this fastener measures 1-1/4 inches in length under the head. It ships in a box of 100 pieces, making it suitable for production assembly, maintenance operations, and general mechanical work. The zinc coating provides basic corrosion resistance for indoor and light-duty applications. Machinists, millwrights, and general maintenance trades will find this a reliable stock fastener for standard UNC threaded assemblies.

This screw is used in a wide range of light to medium-duty fastening applications across residential, commercial, and industrial settings. The 1/4-20 UNC thread is one of the most common inch-series thread sizes, making this screw a go-to for equipment panels, machine guards, junction boxes, brackets, and structural assemblies where a round head profile and Phillips drive access are required. The box quantity of 100 supports shop stocking and repetitive-task workflows.

Key Features

• 1/4-20 UNC thread for compatibility with the most common inch-series tapped holes
• Round head profile provides a low-profile dome appearance with a wide bearing surface
• Phillips drive for use with standard No. 2 Phillips bits and screwdrivers
• Grade 2 steel construction suitable for general-purpose, non-structural fastening
• Zinc-plated finish for basic corrosion resistance in dry or low-humidity environments
• Box of 100 pieces supports shop stock and volume assembly tasks

Compatibility

Designed for use in any standard 1/4-20 UNC tapped hole or with a 1/4-20 hex nut. Suitable for general-purpose mechanical assemblies requiring a round head Phillips machine screw in Grade 2 steel.

Installation Notes

Install with a No. 2 Phillips screwdriver or power driver bit. Ensure the mating hole is properly tapped to 1/4-20 UNC specification before driving. Do not overtorque — Grade 2 steel has lower tensile strength than Grade 5 or Grade 8 fasteners and is not rated for high-stress structural joints. Follow applicable mechanical or electrical codes when fastening equipment enclosures or panels.
