External Shakeproof T-lock Washers

External shakeproof T lock washers provide a high performance anti loosening solution for bolted assemblies exposed to vibration, shock and dynamic loading. Designed with external teeth and a T lock profile, these washers bite firmly into both the mating surface and the underside of the fastener head or nut when tightened, creating strong resistance to rotation. This locking action helps maintain clamp load and joint integrity without the need for additional locking devices. Commonly used in machinery, steelwork, electrical installations, automotive assemblies and general engineering applications, external T lock washers are ideal where reliable vibration resistance is critical. Manufactured to DIN 6797A standards, they are suitable for demanding professional and industrial environments.

Supplied in commonly used metric sizes, external shakeproof T lock washers are available in corrosion resistant finishes including BZP, stainless steel A2 and stainless steel A4 to suit internal, external and aggressive environments. Selected for consistent locking performance, secure engagement and suitability for professional trade and engineering use, external shakeproof T lock washers provide a dependable solution for vibration resistant fastening applications.
