DIN968 Standard Self Tapping Screws
DIN968 is a standard for cross groove pan head self tapping screws established by the German Institute for Standardization (DIN). These screws are commonly utilized for fastening connections of both metal sheets and non-metallic materials.
The groove type for DIN968 standard self tapping screws can be either H-type or Z-type, and the end is either a pointed tail (C-type) or a flat tail (F-type), making it suitable for penetrating hard materials. These screws are designed with Pan Head structures that include gaskets, with diameter specifications ranging from ST2.9 to ST6.3.

DIN968 self-tapping screws find wide usage in various industries such as electrical enclosures, building curtain walls, medical devices, and more. One of its notable features is the built-in pad design, which helps improve force uniformity. This design makes these screws ideal for applications that require anti-loosening properties, especially when working with thin plates.
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.
