Value Collection MPFX03040-050BX M3x0.5 Flat Head Screw 50pk

Product Description

The VALUE COLLECTION MPFX03040-050BX is a metric machine screw with a flat head and Phillips drive, manufactured from 18-8 stainless steel (A2 grade) with a bright, uncoated finish. The screw follows DIN 965 dimensional standards, with an M3x0.5 thread size and an overall length of 40 mm. This fastener is sold in a minimum quantity of 50 pieces per order. Electricians, plumbers, HVAC technicians, and general trade professionals use flat head Phillips machine screws where a flush or countersunk installation is required in metal or thermoplastic assemblies.

This screw is suited for light-duty mechanical assemblies in residential and commercial applications. The M3x0.5 thread is common in panel mounting, enclosure fabrication, and equipment assembly where metric fasteners are specified. The 18-8 A2 stainless steel construction provides corrosion resistance in environments with moisture exposure, making it appropriate for HVAC equipment panels, electrical enclosures, and plumbing fixture components. No washer is included or integrated into the design.

Key Features

• M3x0.5 thread with 40 mm overall length for precise metric fitment
• Flat countersunk head profile per DIN 965 for flush installation
• Phillips drive compatible with standard No. 1 Phillips bits and screwdrivers
• 18-8 stainless steel (A2 grade) for corrosion resistance in damp or outdoor-adjacent environments
• Bright uncoated finish with no additional plating that could affect thread tolerance
• Sold in packs of 50, appropriate for production assembly or service van stock

Compatibility

Designed as a standard DIN 965 metric machine screw for use in any application specifying an M3x0.5 flat head Phillips fastener in 18-8 or A2 stainless steel.

Installation Notes

Install using a No. 1 Phillips screwdriver or bit driver; avoid cam-out by applying firm axial pressure during driving. Countersink the mating material to the appropriate DIN 965 head angle before installation to achieve a flush seating surface. Do not exceed the torque capacity of the M3 thread in soft materials such as aluminum or thermoplastic. For electrical enclosure work, follow applicable NEC requirements for fastener material and panel construction.
