Value Collection MPTI02500750-025B Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPTI02500750-025B is a 1/4-20 UNC machine screw with a truss head and Phillips drive, manufactured from Grade 2 steel with a zinc-plated finish. At 3/4 inches in length measured under the head, this screw delivers reliable clamping force in light- to medium-duty fastening applications. The wide, low-profile truss head distributes load across a broad bearing surface, reducing pull-through risk in thinner materials. Sold in a minimum order quantity of 25 pieces, this fastener is appropriate for general mechanical assembly, HVAC panel work, electrical enclosures, and similar trade applications where a standard inch-series thread is specified.

This machine screw is suited for residential and light commercial assembly tasks where a 1/4-20 UNC thread is required. The zinc-plated finish provides basic corrosion resistance for indoor and protected outdoor environments. Typical applications include securing sheet metal panels, junction box covers, equipment mounting brackets, and access panels in HVAC, electrical, and general mechanical work. The Phillips drive is compatible with standard and magnetic bit drivers used in trade fieldwork.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes and nuts
• Truss head profile provides a wide bearing surface to reduce pull-through in thin materials
• Phillips drive works with common #2 Phillips bits and manual screwdrivers
• Grade 2 steel construction meets general-purpose fastener strength requirements
• Zinc-plated finish offers basic corrosion protection in dry or protected environments
• Sold in packs of 25 to support job-lot stocking and service van inventory

Compatibility

Designed as a general-purpose replacement or stocking fastener for any application requiring a 1/4-20 UNC truss head Phillips machine screw at 3/4 inches in length.

Installation Notes

Install using a standard number 2 Phillips bit driver or manual screwdriver. Ensure the mating hole or nut is tapped to 1/4-20 UNC before driving to avoid cross-threading. Power down and de-energize any electrical or HVAC equipment before removing or replacing panel fasteners. Do not overtighten, as Grade 2 steel has lower proof load values than higher-grade fasteners and is not intended for high-torque structural connections.
