Value Collection 663031PS M2.5x0.45 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 663031PS is a metric machine screw with a flat head and Phillips drive, manufactured from Grade 4.8 steel with a zinc finish. This fastener conforms to DIN 965, the international standard for countersunk flat head screws with Phillips drive. The M2.5x0.45 thread size and 5 mm overall length make it well-suited for low-profile fastening applications where the screw head must sit flush with or below the work surface. Zinc plating provides basic corrosion resistance for general indoor or lightly protected environments. These screws ship in minimum order quantities of 100 units, appropriate for production, assembly, and maintenance shop use.

This screw is used in light mechanical assemblies, electrical enclosures, consumer electronics, instrumentation, and similar applications requiring a small-diameter metric fastener. The flat countersunk head profile is designed for use with pre-countersunk or drilled-and-countersunk holes. Typical installers include mechanical assemblers, electricians working on panel hardware, and maintenance technicians handling metric equipment.

Key Features

• DIN 965 standard flat countersunk head for flush-mount fastening
• M2.5x0.45 metric thread with 5 mm overall length
• Grade 4.8 steel construction for general-purpose strength requirements
• Zinc finish for basic corrosion protection in dry or lightly exposed environments
• Phillips drive compatible with standard No. 1 Phillips bits and drivers
• Sold in multiples of 100 units, suitable for production and stocking use

Compatibility

Designed as a general-purpose DIN 965 metric machine screw for use in any application requiring an M2.5x0.45 flat head Phillips fastener without a washer.

Installation Notes

Installation requires a properly countersunk or pre-formed conical seat to allow the flat head to sit flush. Use a No. 1 Phillips screwdriver or bit at the correct torque for Grade 4.8 fasteners per applicable assembly specifications. Avoid over-driving, which can strip the Phillips recess or damage the countersink seat. Confirm thread engagement depth meets the requirements of the mating material before final assembly.
