Internal Shakeproof Lock Washers

Internal shakeproof lock washers are designed to resist loosening under vibration by using internal serrations that bite into the fastener and mating surface, providing secure locking performance. Commonly used in mechanical, electrical and assembly applications, these washers are ideal where a smooth outer edge is required. Manufactured to DIN 6798J standards and available in A2 and A4 stainless steel and zinc plated finishes, they offer durability and corrosion resistance.

Available in commonly used metric sizes and specifications, these washers ensure secure fastening, improved vibration resistance and dependable performance across engineering, electrical and general assembly applications.
