Why Torque Accuracy Matters for External Tooth Lock Washers

Torque is often overlooked when installing External Tooth Lock Washers, yet it’s one of the most critical factors for effective locking. Under-tightening prevents full tooth engagement, while over-tightening crushes the teeth — both lead to failure under vibration.

 Use a torque wrench and follow manufacturer specifications for best results. The correct torque ensures optimal clamping force without deforming the washer. For stainless steel or coated variants, adjust torque slightly based on surface friction. Proper torque application not only extends the washer’s life but also ensures consistent locking performance in any mechanical or structural assembly.
