DIN 965
DIN 965 is a standard from the German Institute for Standardization (DIN) for countersunk screws with a cross recess. This standard defines the dimensions, tolerances, and mechanical properties of countersunk screws featuring a 90° countersunk head and a Phillips cross-drive. Countersunk screws according to DIN 965 are available in various sizes and materials to suit different requirements.
Features and Dimensions
-
Available in various diameters and lengths, standard thread sizes range from M1.6 to M10
-
Designed so that the head sits flush with the workpiece surface, creating a smooth and even appearance
Materials and Surface Treatments
-
Stainless steel (A2, A4)
-
Brass
-
Aluminium
-
Additional surface treatments include zinc plating, nickel plating, or phosphating for corrosion resistance
Applications
-
Mechanical engineering: fastening parts where a flush surface is required
-
Electrotechnical installations: secure fastening of electrical components
-
Furniture industry: mounting furniture parts without protruding screw heads
-
Automotive industry: securing vehicle components requiring a smooth surface
Assembly and Use
When installing DIN 965 countersunk screws, it's crucial to choose the correct size and material for optimal performance and longevity. The cross drive allows for easy and secure installation with an appropriate screwdriver or power driver.
Conclusion
DIN 965 countersunk screws are essential fastening elements in many mechanical and electrical applications. Their standardized dimensions and materials ensure a reliable and secure connection that meets diverse usage requirements.
