Internal Tooth Lock Washer Metric A2 Stainless Steel

Metric Stainless Steel Internal Tooth Lock Washers

  • Lock assemblies underneath the head of the fastener
  • Often chosen over External Tooth Lock Washers for aesthetic reason
  • Offer a durable and long lasting assembly
  • Corrosion Resistant
  • A2 Stainless steel
