Value Collection 0308MPF 3-48 X 1/2 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 0308MPF is a 3-48 unified coarse thread machine screw designed for light-duty mechanical fastening applications. It features a flat head profile with a Phillips drive recess, allowing it to sit flush with or below the mating surface when installed in a countersunk hole. Constructed from steel with a zinc finish, the 0308MPF meets ASME B18.6.3 and SAE J82 standards. Overall length is 0.5 inches, measured from tip to top of head. This screw is sold individually but requires a minimum order quantity of 100 units. Electricians, panel assemblers, and instrument technicians regularly use fasteners in this size range for securing cover plates, terminal blocks, and small enclosure components.

The 0308MPF is suited for use in electronic assemblies, electrical enclosures, control panels, and precision mechanical devices where a flush or countersunk fastener is required. The 3-48 thread size is a fine-pitch, small-diameter designation common in instrumentation, HVAC control board housings, thermostat assemblies, and light electrical equipment. The zinc finish provides basic corrosion resistance appropriate for indoor service environments.

Key Features

• 3-48 unified coarse thread for use in small-diameter tapped holes
• Flat head design seats flush when installed in a properly countersunk hole
• Phillips drive for standard screwdriver or power-tool installation
• Steel construction with zinc finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 fastener standards
• No washer — installs directly against the mating surface

Compatibility

Designed as a standard inch-series machine screw for any application requiring a 3-48 threaded flat head Phillips fastener per ASME B18.6.3. Verify thread engagement depth and countersink angle of the mating component before installation.

Installation Notes

Install using a Phillips screwdriver or a power driver with a properly sized Phillips bit to avoid cam-out and head damage. Ensure the receiving hole is tapped to 3-48 and the countersink angle matches the flat head geometry before driving. Do not overtighten — small-diameter machine screws are susceptible to thread stripping in soft substrates. Power down any electrical equipment completely before fastening or removing screws on live assemblies.
