Value Collection MPFZX02504-050BX M2.5 Flat Head Machine Screw

Product Description

The VALUE COLLECTION MPFZX02504-050BX is a metric flat head machine screw designed for precision fastening applications where a flush or countersunk finish is required. Manufactured from 18-8 stainless steel (A2 grade), this screw provides solid corrosion resistance in wet or humid environments. The M2.5x0.45 thread size and 4.00 mm overall length make it well-suited for small-component assembly work. The Pozidriv drive interface delivers improved torque transfer compared to standard Phillips, reducing bit cam-out during installation. Sold in a minimum order quantity of 50 pieces, this screw meets DIN 965 standards and carries no additional finish coating, remaining in a bright, uncoated state as supplied.

This fastener is used in light mechanical assembly, electronics enclosures, instrumentation panels, and other applications requiring a small-diameter metric screw with a countersunk head profile. The flat head design seats flush with or below the mating surface when installed into a properly chamfered hole. Trades and assembly technicians working with metric hardware on compact equipment, HVAC controls, electrical enclosures, or similar small-component systems will find this screw appropriate for standard countersunk mounting configurations.

Key Features

• M2.5x0.45 thread size per metric standard, 4.00 mm overall length
• Flat (countersunk) head seats flush for clean, low-profile installations
• Pozidriv drive size 1 mm for reduced cam-out versus standard Phillips
• 18-8 stainless steel, Grade A2 — corrosion resistant without coatings
• Bright/uncoated finish — no plating or treatment that could affect tight tolerances
• Conforms to DIN 965 fastener standard

Compatibility

Designed as a standard DIN 965 metric flat head machine screw suitable for countersunk fastening applications using M2.5x0.45 thread pitch in metal, plastic, or composite assemblies.

Installation Notes

Installation is performed by hand or with a Pozidriv PZ1 bit using a power or manual screwdriver. Ensure the mating hole is properly countersunk to match the flat head angle before driving the screw. Avoid overtightening in soft materials or thin stock, as the small diameter is susceptible to thread stripping. Power down or de-energize any equipment before fastening components inside electrical or control enclosures.
