316 - Stainless steel - Hexagon socket countersunk head screw
Our Grade 316 Stainless Steel Countersunk Screws are engineered for the most demanding environments where both a flush finish and superior corrosion resistance are required. Also known as A4 Marine Grade, these DIN 7991 fasteners contain molybdenum, making them immune to the pitting corrosion often caused by sea water and chlorides. The 90-degree conical flat head sits perfectly level with the surface, providing a streamlined, snag-free finish essential for marine decking, chemical equipment, and high-end architectural glazing.
- Marine Grade A4: Manufactured from AISI 316 stainless steel, offering the highest level of protection against salt spray and industrial pollutants.
- Flush Fit Design: The countersunk head allows for a completely smooth surface profile, reducing drag and preventing dirt accumulation.
- Global Logistics: We maintain a strategic stock of A4 fasteners, ensuring rapid delivery to shipyards and industrial sites worldwide.
