Value Collection MPPI0-400750-100BX 4-40 X 3/4 in Pan Head Screw

Product Description

The VALUE COLLECTION MPPI0-400750-100BX is a 4-40 x 3/4 inch pan head machine screw designed for general-purpose fastening applications. Manufactured from Grade 2 steel with a zinc-plated finish, this screw resists corrosion in standard indoor environments. The Phillips drive allows fast installation with common hand and power tools. The pan head profile sits low and wide against the workpiece, making it a reliable choice for light assemblies, enclosures, and equipment panels. Thread size 4-40 conforms to Unified National Coarse (UNC) standards. This box contains 100 screws measured length-under-head at 3/4 inch. Machinists, assemblers, and maintenance technicians regularly stock this size for routine service and repair work.

This screw is suited for light-duty mechanical assemblies in residential and commercial settings. Common applications include electrical enclosures, control panels, HVAC equipment covers, and general sheet metal or plastic fastening where a small-diameter UNC thread is required. The zinc plating makes it appropriate for dry or minimally humid indoor environments. It is typically installed without a washer and pairs with standard 4-40 threaded inserts or tapped holes.

Key Features

• 4-40 UNC thread for compatibility with standard tapped holes and threaded inserts
• 3/4 inch length measured under head for consistent seating depth
• Pan head geometry distributes clamping load across a wide bearing surface
• Phillips drive accepts standard No. 1 Phillips bits for fast installation
• Grade 2 steel construction provides adequate tensile strength for light-duty fastening
• Zinc-plated finish offers basic corrosion resistance in dry indoor conditions

Compatibility

Designed as a standard 4-40 UNC machine screw suitable for any application requiring a pan head Phillips fastener in that thread size and length.

Installation Notes

Install using a No. 1 Phillips screwdriver or compatible power driver bit. Ensure the mating hole is tapped to 4-40 UNC or fitted with the appropriate threaded insert before driving. Avoid overtorquing, as Grade 2 steel has lower proof load than higher-grade fasteners. Follow applicable equipment manufacturer guidelines and relevant codes when used inside electrical or mechanical enclosures.
