Selecting the right size of an external tooth lock washer is essential for its effectiveness. The inner diameter should fit snugly around the bolt shaft, while the outer diameter should be large enough to cover the contact area without interfering with other components. If the washer is too small, it may not distribute the load effectively; if it’s too large, it may hinder adjacent parts or fail to provide the necessary locking force.
Other factors include the thickness and tooth design—deeper, more aggressive teeth may be required for heavy-duty applications, while finer teeth can suffice for precision electronics. Always consult size guides provided by manufacturers, and test washers under simulated load conditions when possible. Correct sizing ensures optimal vibration resistance and prevents premature wear or failure in your assembly.
