These A4 DIN 97 slotted countersunk woodscrews are manufactured from high-quality 316 stainless steel, providing superior corrosion resistance and long-term durability. Designed as self-tapping screws, they cut their own thread into timber and other suitable materials, delivering a secure, reliable fastening without the need for pre-threading. The A4 marine-grade stainless steel construction makes them ideal for harsh or exposed environments, including marine, coastal, industrial, and outdoor construction settings where resistance to rust, moisture, and chemicals is critical.

The classic slotted drive and countersunk head allow the screw to sit flush with the surface, creating a clean, professional finish that is perfect for joinery, woodworking, decking, cladding, and general construction projects. These woodscrews offer excellent holding power in wood and similar substrates, helping to prevent loosening over time, even under vibration or changing weather conditions.

Engineered to meet DIN 97 standards, they deliver consistent quality, accurate threading, and dependable performance across a wide range of applications. Whether you are working on marine fittings, exterior timber work, industrial installations, or structural fixing in corrosive environments, these 316 stainless steel self-tapping woodscrews offer a strong, long-lasting fastening solution with minimal maintenance requirements.
