These A4 316 stainless steel 6-lobe countersunk self-tapping screws are engineered for high-strength, long-lasting performance in demanding environments. Manufactured to DIN 7982 / 7982T standards, they deliver reliable, secure fastening where superior corrosion resistance and durability are essential.

Made from marine-grade 316 stainless steel, these self-tappers provide outstanding resistance to rust, chemicals, and harsh weather, making them ideal for coastal, offshore, and other corrosive environments. The 6-lobe drive (often referred to as Torx-style) offers excellent torque transfer and reduced cam-out, helping to prevent damage to the screw head and ensuring a clean, professional installation.

The countersunk head allows the screw to sit flush with the material surface, providing a neat finish and reducing snagging or interference with adjacent components. As self-tapping fasteners, they are designed to cut their own mating thread in suitable materials, simplifying installation and reducing the need for pre-tapped holes in many applications.

These stainless steel fasteners are suitable for:

• Marine fixtures, boat building, and coastal installations
• Industrial machinery, equipment assembly, and plant maintenance
• Construction, structural work, and general building projects
• Outdoor installations where long-term corrosion resistance is critical

Combining high tensile strength, stability, and exceptional resistance to rust and chemicals, this range of A4 316 stainless steel countersunk self-tapping screws offers a dependable solution for professional engineers, installers, and DIY users alike. Choose the required size from the range to achieve secure, lasting fixings in your next project.
