DIN968 Overview:
DIN968 is a standard for cross groove pan head self tapping screws
developed by the German Institute for Standardization (DIN). These
screws are commonly used for fastening connections between metal
sheets and non-metallic materials.
Features of DIN968 Screws:
The groove type of DIN968 standard self tapping screws is cross
groove, with variations such as H-type or Z-type. The screw can
have either a pointed tail (C-type) or a flat tail (F-type), making
it suitable for self tapping into hard materials. The head of the
screw is designed as a Pan Head structure with gaskets, and the
diameter specifications range from ST2.9 to ST6.3.
DIN968 self tapping screws are commonly crafted from carbon steel (surface galvanized/nickel) and stainless steel (sus304 corrosion-resistant). For carbon steel grade 8.8, the minimum tensile strength required is ≥ 400MPa, while stainless steel grade A2-70 must meet a strength of ≥ 700MPa. These specifications align with the technical details outlined in the international equivalent standard ISO 7049.

| Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request. | The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements. | The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation. |
