DIN7981 Self Tapping Screw Phillips Pozi Drive Self-Drilling

Product Description:

To specify, DIN7981 screws conform to the German standard and are designed as cross slot pan head self-tapping screws, primarily used for securing connections of thin metal plates or non-metallic materials. The screw features a semi-circular disc head and is available with cross grooves, which can be of the H-shape or Z-shape variety. The screws come with two tail options - a pointed tail known as the C-type or a flat tail known as the F-type. Variants in specifications exist to cater to different application requirements.

Features:

The performance requirements of DIN7981 are as follows:

• The clarity of the screw thread
• The accuracy of the tail tooth lifting
• The alignment of the head axis

These aspects must meet strict standards. Inspection with a cross groove plug gauge is necessary to ensure the matching degree of the batch head and prevent slipping.

Applications:

DIN7981 self-tapping screws find primary applications in electronic appliances, building curtain walls, medical equipment, and packaging machinery. Being effortless to install, these screws eliminate the need for pre-tapping threaded holes. However, they possess a limited load-bearing capacity and are thus unsuitable for high load scenarios.

The technical specifications of DIN7981 self-tapping screws are closely aligned with ISO 7049 and DIN7981 standards, with GB/T 845 serving as the equivalent standard in China. Thus, they maintain a consistent technical quality across different industry benchmarks.

Packaging:

Carton Packaging	Outer Cartonbox Packaging	Pallet Packaging
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.
