Value Collection MSFXX05050-050BX M5x0.8 Flat Head Machine Screw

Product Description

The VALUE COLLECTION MSFXX05050-050BX is a flat head slotted machine screw manufactured from Grade 316 A4 stainless steel with a bright, uncoated finish. Sized at M5x0.8 thread with an overall length of 50 mm, this fastener conforms to DIN 963 dimensional standards. Grade 316 stainless provides elevated corrosion resistance compared to Grade 304, making it well suited for wet, marine, or chemically aggressive environments. The slotted flat head sits flush with or below the mating surface when countersunk correctly, reducing snag points in assembled components. Sold in a minimum order quantity of 50 pieces per box.

This screw is used wherever a flush or countersunk fastener is required in metal or plastic assemblies. Typical applications include mechanical equipment, plumbing fixtures, enclosures, and marine hardware where corrosion resistance is a priority. The metric M5x0.8 thread and DIN 963 form factor make it interchangeable with other DIN-compliant components in European-standard assemblies. Installers working on food-service equipment, chemical processing skids, or coastal installations commonly specify Grade 316 A4 fasteners for long-term serviceability.

Key Features

• Grade 316 A4 stainless steel construction for superior corrosion resistance in harsh or marine environments
• DIN 963 standard ensures dimensional compatibility with other metric flat head slotted fasteners
• M5x0.8 thread pitch with 50 mm overall length covers a wide range of medium-duty fastening applications
• Flat head profile countersinks flush, eliminating protrusion in finished assemblies
• Bright, uncoated finish maintains consistent appearance and does not add dimensional variance from plating
• Box quantity of 50 pieces supports production and service work without per-piece packaging overhead

Compatibility

Designed as a DIN 963-compliant metric machine screw suitable for use with standard M5 tapped holes or nuts in mechanical, plumbing, and electrical enclosure assemblies requiring a flush countersunk fastener.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with metric fastener standards. Before installation, ensure the mating hole is properly countersunk to the DIN 963 head angle to achieve full flush seating. Use a correctly sized flat-blade screwdriver bit to avoid cam-out and head damage. When installing into dissimilar metals, follow standard practice to mitigate galvanic corrosion, particularly in saltwater or high-humidity environments.
