Value Collection MPFX03030-050BX M3x0.5 Flat Head Screw

Product Description

The VALUE COLLECTION MPFX03030-050BX is a metric M3x0.5 flat head Phillips machine screw manufactured from grade 18-8 stainless steel (A2) with a bright, uncoated finish. The screw measures 30 millimeters in overall length and conforms to DIN 965, the international standard for countersunk flat head screws with Phillips drive. This fastener is well suited for applications requiring corrosion resistance without surface plating. Machinists, millwrights, equipment assemblers, and maintenance technicians regularly specify 18-8 stainless hardware where moisture exposure or chemical contact rules out carbon steel fasteners.

This screw is used in light mechanical assemblies, panel mounting, electronics enclosures, marine equipment, food-processing machinery, and general-purpose metric fastening where a flush, countersunk head profile is required. The M3x0.5 thread pitch and 30 millimeter length make it a common selection for thin-to-medium gauge sheet metal and machined component assemblies. It is sold in a minimum order quantity of 50 pieces per box, suited for shop stock and service inventory.

Key Features

• M3x0.5 metric thread with 30 millimeter overall length for precise dimensional fit in DIN-spec assemblies
• Grade 18-8 stainless steel (A2) provides corrosion resistance in wet, outdoor, and light chemical environments
• Flat countersunk head per DIN 965 allows flush installation in countersunk holes
• Phillips drive for compatibility with common power and hand drivers
• Bright uncoated finish maintains consistent dimensions and avoids coating thickness variation in tight tolerances
• Packaged in a box of 50 for shop stock or project quantity use

Compatibility

Designed as an OEM-style and general-purpose replacement or stock fastener for metric M3x0.5 threaded applications requiring a DIN 965 countersunk flat head profile in stainless steel.

Installation Notes

Installation is performed by machinists, assemblers, or maintenance technicians using a Phillips screwdriver or appropriate power driver bit. Confirm the mating material is pre-tapped or pre-threaded to M3x0.5 before installation. To prevent galling, a small amount of anti-seize compound is recommended when threading stainless fasteners into stainless tapped holes. Do not overtighten — stainless steel fasteners are more susceptible to thread galling and shear than carbon steel equivalents.
