Overview
These DIN 25201 external tooth lock washers are precision-engineered for critical M4 bolted connections where vibration resistance is paramount. Designed to meet the rigorous German industrial standard, they provide a robust mechanical locking solution that prevents fastener rotation and loosening under dynamic loads, shock, and thermal cycling. Manufactured from premium 316L stainless steel, they are ideal for applications demanding both high strength and excellent corrosion resistance in challenging environments.
Key Features
Engineered to DIN 25201 standard for guaranteed dimensional consistency and performance Constructed from 316L stainless steel for superior corrosion resistance in harsh conditions Hardened to 800 HV (Vickers hardness) for exceptional spring force and long-term durability External tooth design bites into both the bearing surface and fastener head for a positive, non-slip lock Plain finish suitable for a wide range of industrial and assembly applications Supplied in a convenient bulk package for production and maintenance efficiency
