M12 Type A External Tooth Lock Washer, Stainless Steel A2 (18‑8)

Manufactured from A2 (18‑8) stainless steel, this M12 Type A external tooth lock washer is designed to help prevent loosening caused by vibration and movement in metric assemblies. The external teeth bite into the fastener head and mating surface to provide strong locking action and improved electrical contact. Excellent corrosion resistance makes it well suited for industrial, electrical, and general‑purpose metric applications requiring secure fastening and long‑term durability.
