Value Collection MPRI02506000-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPRI02506000-100BX is a 1/4-20 threaded machine screw with a round head and Phillips drive, manufactured from Grade 2 steel with a zinc-plated finish. It measures 6 inches in length under head, making it suited for deeper fastening applications where a standard-length screw falls short. The zinc plating provides basic corrosion resistance for general indoor and light-duty use. This screw conforms to ASME B18.6.3 dimensional standards, ensuring consistent head geometry and thread form. Trade professionals and maintenance technicians rely on this fastener for panel assembly, equipment mounting, and structural component attachment across a range of industrial and commercial applications.

This screw is used in general mechanical assembly, HVAC equipment panels, electrical enclosures, and light structural fabrication. The 1/4-20 thread is one of the most common unified coarse thread sizes in North American trade work, compatible with standard 1/4-20 tapped holes and nuts. The round head profile sits above the work surface and distributes clamping load evenly, while the Phillips drive is compatible with standard power and manual drivers. Applications span residential and commercial settings where a medium-strength, zinc-finished carbon steel fastener is appropriate.

Key Features

• 1/4-20 unified coarse thread for compatibility with standard tapped holes and hardware
• 6-inch length under head accommodates deeper fastening requirements
• Round head Phillips drive works with standard power drivers and hand screwdrivers
• Grade 2 steel construction provides adequate strength for general-purpose mechanical assembly
• Zinc-plated finish offers basic corrosion resistance for indoor and light-duty environments
• Conforms to ASME B18.6.3 for consistent dimensional tolerances

Compatibility

Designed as a general-purpose replacement or stock fastener for any application requiring a 1/4-20 coarse thread machine screw with a round Phillips head and 6-inch body length.

Installation Notes

Installation is performed by maintenance technicians, electricians, HVAC mechanics, or general trade personnel using a Phillips screwdriver or Phillips-bit power driver. Always ensure the mating tapped hole or nut is clean and free of debris before driving. Do not overtighten, as Grade 2 steel has lower proof load than higher-grade fasteners. When used in electrical enclosures or panels, verify that fastener installation complies with applicable NEC requirements for the assembly type.
