Value Collection MPRI02501000-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPRI02501000-100BX is a 1/4-20 x 1-inch round head Phillips machine screw manufactured from Grade 2 steel with a zinc-plated finish. It uses Unified National Coarse (UNC) threading at 1/4-20 and measures 1 inch in length under the head. The zinc plating provides baseline corrosion resistance suitable for general-purpose fastening applications. This screw is sold in a box of 100 and is commonly installed by HVAC technicians, electricians, plumbers, sheet metal workers, and general contractors when securing panels, brackets, and equipment housings in both residential and light commercial settings.

This fastener is appropriate for general mechanical assembly and equipment installation tasks where a 1/4-20 UNC thread is specified. The round head profile sits above the mating surface, making it well suited for applications where a flush mount is not required. The Phillips drive allows installation with standard Phillips screwdrivers or power drivers. Typical use cases include securing electrical enclosure panels, HVAC equipment covers, and light structural brackets. The box quantity of 100 supports stocking for service vehicles or shop inventory.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 1-inch length measured under the head for consistent engagement depth
• Round head profile provides a wide bearing surface without requiring a countersunk hole
• Phillips drive accepts standard Phillips No. 2 bits and screwdrivers
• Zinc-plated Grade 2 steel finish offers general corrosion resistance in dry to mildly humid environments
• Sold in a box of 100 for efficient stocking and service use

Compatibility

Designed as a general-purpose 1/4-20 UNC machine screw suitable for use with any standard 1/4-20 tapped hole, hex nut, or coupling nut in equipment panels, brackets, and enclosures.

Installation Notes

Install with a Phillips No. 2 screwdriver or power driver bit. De-energize any electrical equipment before fastening or removing screws on live panels in accordance with applicable NEC guidelines. Do not overtighten into thin sheet metal or plastic to avoid stripping the mating thread. Inspect zinc plating for damage before use in environments with prolonged moisture exposure.
