Value Collection MSFXX04030-050BX M4x0.7 Flat Head Screw 50pk

Product Description

The VALUE COLLECTION MSFXX04030-050BX is a metric flat head slotted machine screw manufactured from Grade 316 stainless steel (A4) with a bright, uncoated finish. The M4x0.7 thread and 30 mm overall length make it a standard fastener for corrosion-resistant assemblies in marine, food service, and industrial environments. Sold in a minimum order quantity of 50 pieces per box, this screw conforms to DIN 963 dimensional standards. The flat head profile allows the fastener to sit flush with or below the surface of the mating material when countersunk correctly. Licensed trades and maintenance professionals specify this grade for environments with prolonged moisture or chemical exposure.

This machine screw is suited for general mechanical assembly, panel mounting, and equipment fabrication where a flush fastener surface is required. The slotted drive accepts standard flat-blade screwdrivers and is compatible with manual and low-torque power tools. Grade 316 A4 stainless steel provides superior chloride resistance compared to Grade 304, making this screw appropriate for coastal, washdown, and process-industry applications. It is commonly used by millwrights, maintenance electricians, plumbers, and equipment fabricators installing or servicing metal enclosures, brackets, and covers.

Compatibility

Designed as a DIN 963-compliant metric machine screw for use in any application requiring an M4x0.7 flat head slotted fastener in Grade 316 stainless steel.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using the appropriately sized flat-blade screwdriver or bit. Confirm that the mating material is countersunk to the correct DIN 963 angle before driving the screw to avoid head deformation. Do not use impact drivers at high torque settings on small-diameter metric screws, as this risks thread stripping or head damage. Inspect threads on both the fastener and the receiving hole for contamination or damage before assembly.
