Value Collection MPFX03020-100BX M3x0.5 Flat Head Screw 18-8

Product Description

The VALUE COLLECTION MPFX03020-100BX is a metric machine screw with a flat head and Phillips drive, manufactured from 18-8 stainless steel with a bright, uncoated finish. It conforms to DIN 965, the international standard for flat countersunk head screws with Phillips drive. The M3x0.5 thread pitch and 20 mm overall length make it a compact, corrosion-resistant fastener suited for light-duty mechanical assemblies. Licensed trades and maintenance technicians working in HVAC panels, electrical enclosures, and plumbing fixture brackets commonly specify 18-8 stainless hardware for its balance of strength and rust resistance in moderate environments. This SKU ships in a box of 100 pieces.

This screw is appropriate for use in residential and light commercial applications where a flush-mounted fastener is required in a tapped hole or with a nut. The flat countersunk head seats flush with or below the mating surface, eliminating protrusion in finished panels, equipment housings, or access covers. The Phillips drive is compatible with standard No. 1 Phillips bits. The M3x0.5 thread is a fine-pitch metric size used frequently in control boards, terminal blocks, enclosure covers, and small mechanical components found in HVAC and electrical equipment.

Installation Notes

Install using a No. 1 Phillips screwdriver or powered driver with a matching bit to avoid cam-out and head damage. Ensure the mating material is tapped to M3x0.5 or that a suitable nut is used - do not force threads. Power down or de-energize any electrical enclosure or control panel before removing or installing fasteners inside live equipment. 18-8 stainless screws are not rated for galvanic compatibility with all metals; verify material pairing when installing in aluminum or dissimilar-metal assemblies in wet locations.
