Internal Shakeproof T-lock Washers

Internal shakeproof T lock washers provide a high performance anti loosening solution for bolted assemblies where vibration resistance is required while maintaining a clean outer edge. Designed with internal teeth and a T lock profile, these washers grip firmly against the underside of the bolt head or nut when tightened, creating strong resistance to rotation without marking the external surface. This makes them ideal for applications where surface finish and component protection are important. Commonly used in machinery, electrical assemblies, enclosures, automotive components and general engineering applications, internal T lock washers help maintain clamp load and joint integrity under vibration and dynamic loading. Manufactured to DIN 6797J standards, they offer reliable locking performance in professional workshop and site environments.

Supplied in commonly used metric sizes, internal shakeproof T lock washers are available in corrosion resistant finishes including BZP and stainless steel A2 to suit internal and protected external applications. Selected for consistent locking action, secure engagement and suitability for professional trade and engineering use, internal shakeproof T lock washers provide a dependable solution for vibration resistant fastening where a smooth external profile is required.
