Value Collection 656204PS M2x0.4 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 656204PS is a flat head slotted machine screw designed for metric fastening applications in light fabrication, assembly, and maintenance work. Built to Grade 4.8 steel with a zinc finish for basic corrosion resistance, this screw meets DIN 963 and ISO 2009 standards for flat head slotted fasteners. The M2x0.4 thread size and 4 mm overall length make it suited to small-component assembly where a flush-seating countersunk head is required. Sold in a package quantity of 1 with a minimum order quantity of 100 units, this screw is a standard metric consumable stocked by maintenance, manufacturing, and field service professionals.

This fastener is used in light-duty metal and mechanical assemblies where a low-profile, countersunk seating surface is needed. The flat head profile allows the fastener to sit flush with or below the mating surface when installed in a properly chamfered or countersunk hole. Typical applications include small equipment panels, electrical enclosures, and precision component housings. The zinc finish provides a basic level of protection suitable for indoor or sheltered environments. This screw is a metric-standard fastener appropriate for any trade or application calling for DIN 963 or ISO 2009 compliance.

Key Features

• Flat countersunk head profile seats flush for clean, low-profile installations
• Slotted drive compatible with standard flat-blade screwdrivers
• Grade 4.8 steel construction meets DIN 963 and ISO 2009 standards
• Zinc finish provides basic corrosion resistance for indoor environments
• M2x0.4 thread with 4 mm overall length for small-component fastening
• Metric system of measurement for use in DIN and ISO spec applications

Compatibility

Designed as a standard metric replacement or stock fastener for any application specifying a DIN 963 or ISO 2009 flat head slotted machine screw in M2x0.4 thread size and 4 mm length.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted drive to avoid cam-out and head damage. The mating hole should be countersunk to the appropriate DIN 963 angle to achieve a flush seating surface. Do not overtighten Grade 4.8 fasteners in soft base materials, as this grade is not rated for high-torque or structural applications. No power-down or lockout procedure is required for fastener replacement alone, but always follow the applicable safety protocols for the assembly being serviced.
