Value Collection MPFI0-400750-100BX 4-40 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION MPFI0-400750-100BX is a 4-40 x 3/4-inch flat head Phillips machine screw designed for general mechanical assembly applications. Manufactured from Grade 2 steel with a zinc-plated finish, this screw offers corrosion resistance suitable for indoor and light-duty environments. The flat head profile sits flush with or below the mating surface when countersunk, making it a common choice in panel assembly, enclosure work, and light-gauge metal fastening. This package contains 100 screws. Thread type is UNC (Unified National Coarse) in the 4-40 designation. Length is measured as overall length at 3/4 inches. No washer is included or integrated.

These screws are used in electrical enclosures, control panels, HVAC equipment covers, and general sheet metal or plastic assembly where a flush-mount fastener is required. The 4-40 thread size is standard in light-duty mechanical and electrical assemblies, including instrument panels and small equipment housings. The Phillips drive allows use with common hand and power tools. Suitable for residential and commercial service work where a low-profile fastener is needed.

Installation Notes

Installation should be performed by a qualified technician or tradesperson familiar with the equipment being serviced. Power down and de-energize any electrical equipment before fastener replacement or panel reassembly. Use a properly sized Phillips screwdriver or bit to avoid cam-out and head damage. Do not overtighten into plastic or thin sheet metal; hand-snug plus a quarter turn is typically appropriate for light-gauge materials.
