DIN 966
DIN 966 is a standard from the German Institute for Standardization (DIN) for countersunk lens-head screws with a cross recess. This standard defines the dimensions, tolerances, and mechanical properties of screws with a 90° countersunk lens head and a Phillips cross-drive. Screws according to DIN 966 are available in various sizes and materials to meet different requirements.
Features and Dimensions
-
Available in various diameters and lengths, common thread sizes range from M2 to M10
-
Lens-shaped top with a 90° countersink, ensuring the head sits flush with the workpiece surface and offers an aesthetic appearance
Materials and Surface Treatments
-
Stainless steel (A2, A4)
-
Brass
-
Surface treatments available for corrosion resistance, such as zinc plating, nickel plating, or phosphating
Applications
-
Mechanical engineering: fastening parts where a flush and visually pleasing surface is required
-
Electrotechnical industry: secure fastening of electrical components and housings
-
Furniture manufacturing: mounting furniture parts with non-protruding screw heads
-
Automotive sector: securing vehicle components that require a smooth, attractive surface
Assembly and Use
For installation, it's important to choose the right size and material to ensure optimal performance and longevity. The cross recess allows easy and secure installation with a suitable screwdriver or power tool.
Conclusion
DIN 966 countersunk lens-head screws are essential fastening elements in many mechanical and electrical applications. Their standardized dimensions and materials provide a reliable, secure connection that meets varied demands and provides a visually appealing finish.
