Value Collection MSFXX04050-050BX M4x0.7 Flat Slotted Screw 50mm

Product Description

The VALUE COLLECTION MSFXX04050-050BX is a metric flat head slotted machine screw manufactured from Grade 316 stainless steel with a bright, uncoated finish. Conforming to DIN 963, this fastener features an M4x0.7 thread and an overall length of 50mm (approximately 1.97 inches). The countersunk flat head profile seats flush with the mating surface when installed in a properly dimensioned countersink. Grade 316 A4 stainless steel provides elevated corrosion resistance compared to 304 grade, making this screw appropriate for wet, marine, and chemically aggressive environments. These fasteners are used by electricians, plumbers, HVAC technicians, and general mechanical tradespeople when a metric fastener with high corrosion resistance is required.

This screw is suited for light-duty mechanical assemblies, panel fastening, equipment enclosures, and fixture mounting where a flush surface finish is required. The DIN 963 standard governs the head geometry, ensuring dimensional interchangeability with other DIN 963-compliant hardware. The M4x0.7 thread pitch is a standard coarse metric thread widely used in instrumentation, control panels, and light structural assemblies across HVAC, plumbing, and electrical trade applications. Sold in a minimum order quantity of 50 pieces per box.

Key Features

• Grade 316 A4 stainless steel construction for superior corrosion resistance in wet and marine environments
• DIN 963 standard flat head geometry for flush countersunk installation
• M4x0.7 coarse metric thread — 50mm overall length
• Slotted drive compatible with standard flat-blade screwdrivers
• Bright uncoated finish — no coating to chip, flake, or contribute galvanic concerns with stainless mating hardware
• Sold in boxes of 50 for jobsite and shop inventory stocking

Compatibility

Designed as a DIN 963-standard M4x0.7 flat head slotted machine screw for use in any application requiring a metric coarse-thread countersunk fastener in that size and grade.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted head. The receiving material must be drilled and countersunk to the correct DIN 963 angle — typically 90 degrees — to achieve a flush seating surface. When installing into threaded metal components, confirm thread engagement depth meets engineering minimums for the load applied. Avoid mixing stainless steel fasteners with dissimilar metals in high-moisture environments where galvanic corrosion could occur.
