Description

Lock Washers Countersunk External Tooth in steel with zinc plating, size #12, is engineered to prevent loosening under vibration and dynamic loads. The countersunk profile sits flush against the surface, while the external teeth bite into the substrate for a secure grip across industrial and light engineering applications.

  • Material: High-strength steel with durable zinc coating for corrosion resistance and long service life.
  • Design: Countersunk shape plus external teeth ensures a flush fit and effective locking action.
  • Locking Action: External teeth bite into the work surface to resist loosening from shock and vibration.
  • Size: #12 — compatible with standard fasteners in automotive, machinery, and construction projects.
  • Applications: Ideal for equipment housings, machinery assemblies, outdoor installations, and anywhere vibration is a concern.

For best results, install with the washer seated evenly under the bolt head and tighten to the appropriate torque. The zinc coating provides additional corrosion resistance in challenging environments.
