Value Collection 656316PS M3x0.5 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 656316PS is a metric machine screw with a flat head and slotted drive, manufactured from Grade 4.8 steel with a zinc finish. Conforming to DIN 963 and ISO 2009 standards, this fastener features an M3x0.5 thread size and an overall length of 16 mm. The zinc coating provides basic corrosion resistance suitable for general indoor mechanical assemblies. This screw is sold in minimum order quantities of 100 pieces and is installed by machinists, millwrights, electricians, and general maintenance technicians working with metric-threaded components.

This fastener is suited for light-duty fastening applications in metal, plastic, and composite assemblies where a flush or countersunk head profile is required. The flat head design allows the screw to sit flush with or below the surface of the mating material when used with a properly countersunk hole. Typical applications include panel fastening, equipment enclosures, and fixture assembly in industrial and commercial maintenance settings.

Key Features

• Flat countersunk head profile for flush installation in countersunk holes
• Slotted drive compatible with standard flat-blade screwdrivers
• M3x0.5 metric thread conforms to DIN 963 and ISO 2009 standards
• Grade 4.8 steel construction for general-purpose mechanical strength
• Zinc finish provides basic corrosion resistance for indoor applications
• No washer — installs directly against the mating surface

Compatibility

Designed as a general-purpose metric machine screw for use in any application requiring an M3x0.5 flat head slotted fastener conforming to DIN 963 or ISO 2009 specifications.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver sized to the slotted head. The mating hole should be countersunk to the appropriate DIN 963 angle to achieve a proper flush seating of the flat head. Do not overtighten Grade 4.8 fasteners in soft materials, as the lower tensile rating relative to higher-grade hardware increases the risk of thread stripping. Power down or de-energize any equipment before servicing fasteners on electrical enclosures or live assemblies.
