Value Collection 656816PS M8x1.25 Flat Head Slotted Screw 16mm

Product Description

The VALUE COLLECTION 656816PS is a metric machine screw with a flat head and slotted drive, manufactured from Grade 4.8 steel with a zinc finish. It carries an M8x1.25 thread and a 16 mm overall length, conforming to DIN 963 and ISO 2009 standards. The flat head profile sits flush with the mating surface when fully driven, making it appropriate for assemblies where a low-profile or countersunk finish is required. This fastener is used across mechanical, electrical, and light structural applications where metric hardware is specified. Sold in a minimum order quantity of 100 pieces per package, it is suited for shop stock and maintenance inventory.

This screw is intended for general-purpose fastening in metric-dimensioned assemblies found in industrial equipment, enclosures, panels, and machinery. The zinc coating provides baseline corrosion resistance in indoor and light-duty environments. The slotted drive is compatible with standard flat-blade screwdrivers and manual drive tools commonly found in trade and maintenance settings. Grade 4.8 designates a medium-strength carbon steel fastener suitable for non-critical clamping and assembly applications where high tensile load is not a primary requirement.

Key Features

• M8x1.25 thread for compatibility with standard metric tapped holes and nuts
• 16 mm overall length suits moderate material stack thicknesses
• Flat head profile allows flush or countersunk installation
• Slotted drive accepts standard flat-blade screwdrivers
• Zinc finish provides basic corrosion protection for indoor use
• Conforms to DIN 963 and ISO 2009 dimensional standards for consistent fitment

Compatibility

Designed as a standard metric replacement or stock fastener for any application requiring an M8x1.25 flat head slotted machine screw conforming to DIN 963 or ISO 2009.

Installation Notes

Use a properly sized flat-blade screwdriver matched to the slot width to avoid cam-out and head damage. Ensure the mating material is tapped or drilled to the correct M8x1.25 specification before driving. Do not overtighten Grade 4.8 fasteners in applications requiring higher clamp load — consult the assembly specification for torque requirements. Handle zinc-coated fasteners with care to avoid stripping the coating, which reduces corrosion resistance.
