What is another word for lock washer?
Pronunciation: [lˈɒk wˈɒʃə] (IPA) 
A lock washer is a vital component in keeping bolts and nuts securely in place. There are various types of lock washers available, such as split washers, toothed washers, and external tooth lock washers. Split washers, also known as helical spring washers, feature a split in the washer's circumference that allows it to compress when bolted. Toothed washers or internal tooth lock washers have teeth on the inside that grip onto nuts and bolts to keep them from loosening. External tooth lock washers, on the other hand, have teeth on the outside that grip onto the surface to prevent the bolt or nut from loosening. Understanding the different types of lock washers is crucial to ensure the right one is used in various applications.
