DESCRIPTION

Precision-engineered M20 Castle Nut (DIN 935) built for heavy-duty fastening in industrial and mechanical applications. The castellated (slotted) design enables secure locking with a cotter pin, preventing loosening under vibration—ideal for machinery, automotive systems, and structural assemblies.

This 3D model is created with accurate real-world dimensions, clean topology, and optimized geometry. Perfect for CAD assemblies, rendering, product visualization, and 3D printing, it offers high detail while maintaining efficient performance for professional use.
