Value Collection 656440PS M4x0.7 Flat Head Slotted Screw 40mm

Product Description

The VALUE COLLECTION 656440PS is a metric machine screw with a flat head and slotted drive, manufactured from Grade 4.8 steel with a zinc finish. The screw features an M4x0.7 thread and an overall length of 40 mm, conforming to DIN 963 and ISO 2009 dimensional standards. Flat head geometry allows the fastener to sit flush with or below the mating surface when countersunk. This screw is installed by maintenance technicians, millwrights, and assembly workers wherever a low-profile, flush-mount fastener is required. Sold in a minimum order quantity of 100 pieces per package.

This fastener is suited for general-purpose metal assembly and light mechanical applications where metric thread sizing is required. The zinc coating provides a basic level of corrosion resistance appropriate for indoor and protected environments. The slotted drive accepts a standard flat-blade screwdriver, making it accessible in most field and shop tool kits. Applications include equipment panels, enclosures, fixtures, and general fabrication work calling for an M4 metric thread pitch.

Key Features

• M4x0.7 metric thread for compatibility with standard M4 tapped holes
• 40 mm overall length with flat head geometry for flush or countersunk installation
• Grade 4.8 steel construction meets DIN 963 and ISO 2009 standards
• Zinc finish provides basic corrosion resistance for indoor and protected use

Compatibility

Designed as a standard metric replacement or stock fastener for any application requiring an M4x0.7 flat head slotted machine screw conforming to DIN 963 or ISO 2009 specifications.

Installation Notes

Install using a flat-blade screwdriver sized to the slotted recess; an undersized driver risks cam-out and head damage. Ensure the mating hole is properly countersunk to accept flat head geometry before driving. De-energize and lock out any electrical enclosure or powered equipment before accessing fastened panels. Grade 4.8 steel is not rated for high-temperature or heavily corrosive environments; evaluate finish suitability before use in outdoor or wet service conditions.
