Metric Stainless A2 (18 8) External Serrated Tooth Lock Washer, DIN 6798A
Our Metric Stainless Steel A2 (18‑8) External Serrated Tooth Lock Washers manufactured to DIN 6798A are corrosion‑resistant locking components designed to prevent loosening in assemblies subjected to vibration, shock, or movement. Made from A2 stainless steel (18‑8 / Type 304 equivalent), these washers provide excellent resistance to rust, oxidation, and general environmental exposure.
The DIN 6798A external tooth design features sharp serrated teeth located on the outside diameter of the washer. When tightened, these teeth bite into both the fastener head and the mating surface, creating strong resistance to rotation and maintaining preload. This design also promotes electrical continuity, making these washers suitable for grounding and electrical applications.
Engineered for dependable locking performance, A2 Stainless DIN 6798A External Serrated Tooth Lock Washers are commonly used in electrical assemblies, motors, equipment enclosures, machinery, automotive components, and general industrial installations. The external tooth profile provides a larger contact area and stronger locking action than internal tooth styles, while stainless steel construction ensures long service life in moisture‑exposed environments. Available in a wide range of metric sizes, these lock washers deliver a reliable fastening solution for OEM production, maintenance, and repair operations where vibration resistance and corrosion protection are required.
