Internal Shakeproof Lock Washers

Internal shakeproof lock washers provide an effective anti-loosening solution for bolted assemblies where vibration resistance is required without marking the outer surface. Designed with internal serrations, these washers grip the underside of the bolt head or nut when tightened, creating resistance to rotation while keeping the outer edge smooth. This makes them ideal for applications where surface protection or a clean external appearance is important. Commonly used in machinery, electrical assemblies, enclosures, automotive components and general engineering applications, internal shakeproof lock washers help maintain clamp load and joint integrity under vibration and movement. Manufactured to DIN 6798J standards, they offer reliable locking performance in both workshop and site environments.

Supplied in commonly used metric sizes, internal shakeproof lock washers are available in corrosion resistant finishes including BZP, stainless steel A2 and stainless steel A4 to suit internal, external and demanding environments. Selected for consistent locking action, correct fit and dependable performance, internal shakeproof lock washers provide a practical, professional solution for vibration resistant fastening applications.
