Product Overview

DIN7981 screws are German standard cross slot pan head self-tapping screws, primarily designed for fastening connections of thin metal plates or non-metallic materials.

Available with pointed tail (C-type) or flat tail (F-type) options, different specifications can be selected based on application requirements.

Key Features

Manufactured to strict DIN7981 standards for thread clarity and dimensional accuracy
Precision-engineered tail tooth lifting for optimal performance
Perfect head axis alignment prevents slipping during installation
Rigorous quality control ensures batch consistency
