Value Collection MSFXX04040-050BX M4x0.7 Flat Head Screw 316 Ss

Product Description

The VALUE COLLECTION MSFXX04040-050BX is a flat head slotted machine screw manufactured from Grade 316 A4 stainless steel with a bright, uncoated finish. Conforming to DIN 963, this metric fastener features an M4x0.7 thread and an overall length of 40 millimeters. The countersunk flat head profile seats flush with the mating surface when installed in a properly chamfered hole. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, making these screws well suited for demanding environments where standard carbon steel fasteners would degrade. Sold in a box of 50 pieces, this SKU ships as a single package.

These DIN 963 flat head slotted screws are used across a wide range of industrial, mechanical, and maintenance applications requiring a flush-mount fastener in a metric M4 size. Common installation scenarios include light equipment assembly, panel and enclosure work, and marine or wet-environment applications where Grade 316 A4 stainless corrosion resistance is specified. The slotted drive accepts a standard flat-blade screwdriver, making tooling requirements minimal. They are appropriate for use in both residential and commercial trade work wherever a metric DIN-standard fastener is called for.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slotted drive without play to avoid cam-out and head damage. The mating component should be drilled and countersunk to the correct DIN 963 angle to achieve a proper flush-seat condition. Torque to the fastener specification established by the equipment manufacturer or applicable mechanical standard. In marine or chemical environments, ensure mating hardware is also 316 stainless or a compatible alloy to prevent galvanic corrosion.
