Product Overview

DIN7981 screws are self-tapping screws with a pan head design and cross slots that adhere to German standards. They are commonly used for fastening thin metal plates or non-metallic materials. The head type features a semi-circular disc head, with groove options like H-shaped or Z-shaped cross grooves. These screws come with a choice of pointed tail (C-type) or flat tail (F-type), allowing selection based on application requirements.

Key Features

Manufactured to strict DIN standards for thread clarity and dimensional accuracy
Precision-engineered tail tooth lifting for optimal performance
Rigorous quality control ensures proper head axis alignment
Cross groove plug gauge testing prevents slipping and ensures batch consistency

Industrial Applications

DIN7981 self-tapping screws are widely used in electronic appliances, building curtain walls, medical equipment, and packaging machinery. Their self-tapping design eliminates the need for pre-tapped threaded holes, simplifying installation. These screws comply with international standards including ISO 7049 and DIN7981, and align with Chinese standard GB/T 845.

Note: While convenient for many applications, these screws have limited load-bearing capacity and are not recommended for high-load situations.
