RS PRO Pozidriv Countersunk Stainless Steel Machine Screw M6 12 mm A4 316 Marine Grade 158-3714

RS PRO 158-3714 Pozidriv Countersunk Stainless Steel Machine Screw M6 12 mm is engineered from premium A4 316 stainless steel, often referred to as marine grade due to its exceptional resistance to chloride-induced corrosion and extreme temperature conditions. This screw features a flat countersunk head designed to sit flush with or below the surface of materials when fitted into pre-drilled, countersunk holes, ensuring a neat and streamlined finish.

The Pozidriv drive recess provides eight points of contact between the screw and screwdriver, offering enhanced grip and reducing the likelihood of cam-out during installation or removal. This particular machine screw adheres to DIN 965Z standards, guaranteeing a consistent thread profile and mechanical properties for industrial and commercial quality assurance.

With a metric M6 thread and 12 mm length, this fastener is ideal for joining components with pre-tapped holes, widely used in industrial machinery, vehicle engines, and precision assemblies. Its corrosion resistance and strength make it suitable for challenging environments such as marine installations, chemical processing plants, dairy and medical sterilization equipment, and sewerage treatment systems.

Countersunk Machine Screws like this one are preferred when a flat surface is paramount, either for aesthetic reasons or to allow other parts to be mounted above the fastener. The head can also be easily concealed with a screw cap, enhancing the finished product's appearance.
