Value Collection 0403MPU 4-40 X 3/16 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 0403MPU is a 4-40 threaded machine screw designed for precision fastening applications in light-duty mechanical and electrical assemblies. It features a flat head profile with a Phillips drive and is manufactured from steel with a zinc finish for basic corrosion resistance. At 3/16 inches overall length, this screw is sized for thin-panel and close-tolerance work where a low-profile, countersunk head is required. The Grade J82 designation indicates compliance with SAE J82 and ASME B18.6.3 standards. This fastener is commonly installed by electricians, mechanical assemblers, and equipment technicians working on control panels, enclosures, and instrumentation hardware.

This screw is suited for use in light-gauge metal, plastic, and composite assemblies where a 4-40 threaded insert or tapped hole is present. Typical applications include control enclosure assembly, electronics mounting, instrument panel work, and HVAC equipment sub-assembly. The flat head design sits flush with or below the material surface, making it appropriate for applications where clearance above the fastener is limited. It ships in packages of 1, with a minimum order quantity of 100 pieces.

Key Features

• 4-40 thread size, 3/16 inches overall length for tight-clearance assemblies
• Flat head profile provides flush or countersunk seating
• Phillips drive compatible with standard and powered screwdrivers
• Steel construction with zinc finish for corrosion resistance
• Meets ASME B18.6.3 and SAE J82 standards
• No washer — bare shank design for clean seating in countersunk holes

Compatibility

Designed as a standard 4-40 machine screw replacement for any application requiring a flat head Phillips fastener with ASME B18.6.3 and SAE J82 compliance in inch-measurement systems.

Installation Notes

Installation is performed with a Phillips screwdriver or powered driver set to appropriate torque for the mating material. Ensure the receiving hole is properly tapped or fitted with a 4-40 threaded insert before driving. For metal panels, deburr and countersink to the correct angle to achieve full flat-head seating. Avoid over-driving, which can strip the 4-40 thread or crack plastic substrates.
