M10 Type J Internal Tooth Lock Washer, Stainless Steel A2 (18‑8)

Manufactured from A2 (18‑8) stainless steel, this M10 Type J internal tooth lock washer is designed to help prevent loosening caused by vibration and movement in metric assemblies. The internal teeth bite into the underside of the fastener head and the mating surface, providing secure locking action while maintaining a low‑profile fit. Excellent corrosion resistance makes it ideal for industrial, electrical, and general‑purpose metric applications requiring reliable fastening and long‑term durability.
