The Role of External Tooth Lock Washers in Vibration Control

External Tooth Lock Washers play a vital role in securing joints that experience constant vibration. Their outward-facing teeth dig into both the fastener and surface, preventing rotation and loosening. However, improper installation or use of incompatible materials can reduce their effectiveness.

 For vibration-prone environments — such as machinery, engines, or transportation — always use stainless steel or hardened steel washers with clean surfaces and proper torque application. When used correctly, these washers act as mechanical insurance, keeping every connection stable, tight, and resistant to motion-induced failure.
