These A4 stainless steel slotted countersunk self-tapping screws are engineered for reliable, long-lasting fastening in the most demanding environments. Manufactured from 316 marine grade stainless steel to DIN 7972, they offer outstanding corrosion resistance, making them ideal for use in marine, industrial, construction, and outdoor applications where exposure to moisture, salt, or harsh weather is expected.

Designed with a slotted countersunk head, these self-tapping screws sit flush with the material surface once installed, providing a clean, professional finish that reduces snagging and improves appearance. The self-tapping thread cuts its own mating thread into pre-drilled holes in materials such as metals, plastics, and some hardwoods, helping to speed up installation and deliver a secure, vibration-resistant hold.

Available in a wide range of gauges and lengths, this selection allows you to choose the right combination for light, medium, and heavy-duty fastening tasks. Whether you are fixing marine hardware, fabricating stainless assemblies, securing cladding, or carrying out general engineering and maintenance work, these screws provide a strong, dependable solution.
