• Consistent thickness control (1.4-1.6mm) for uniform pressure distribution and reliable clamping force
• External tooth configuration provides maximum surface contact for enhanced grip without damaging softer materials

Professional Applications & Engineering Value

These M24 external tooth lock washers deliver critical vibration-resistant fastening solutions for demanding industrial applications. Manufactured from 18-8 stainless steel, they offer exceptional corrosion resistance ideal for chemical processing, marine environments, and outdoor equipment. The external tooth design according to DIN 6798 ensures positive locking action by digging into both the fastener head and bearing surface, effectively preventing rotational loosening caused by machinery vibrations, thermal cycling, or dynamic loads. This makes them particularly valuable for assembly lines, heavy machinery, automotive components, and electrical enclosures where secure locking performance is essential for operational safety and reduced maintenance intervals. The metric dimensions (25mm ID, 38mm OD) provide precise compatibility with M24 fasteners across European-engineered equipment and global industrial standards.
