Pozi Countersunk A4 Stainless Steel Screws | Duchy Fasteners

These precision-engineered countersunk machine screws are manufactured from high-grade A4 / 316 stainless steel for outstanding strength, durability, and corrosion resistance. Designed to meet DIN 965 specifications, they provide a reliable fastening solution wherever a flush, professional finish is required.

Engineered for demanding environments, these stainless steel fasteners are particularly suited to marine, offshore, and coastal applications where exposure to moisture, salt, and harsh weather is common. Their superior corrosion resistance also makes them ideal for industrial machinery, construction projects, engineering assemblies, and general maintenance tasks.

The recessed countersunk head allows the screw to sit flush with the surface once installed, reducing snagging and providing a clean, streamlined appearance. This makes them perfect for applications in metalwork, timber fabrication, panel fixing, and equipment enclosures where both performance and appearance matter.
