In addition to the wealth of information you have learned while perusing the article, there are a few additional facts associated with bent tab washers, including the following:

  • When utilizing these washers, the tabs are often bent around the hex nut to secure it. It is recommended that these tabs are only bent once as they tend to crystallize if bent a second time.
  • As you can imagine, once the tab is bent and everything is secured into place, it can be difficult to disassemble a bent tab washer. There are special tools available for this action, but you can also use pliers, paint can openers, and flat-head screwdrivers.
  • Older bent tab washers are harder to utilize, so if possible, replace old washers with newer types for easier access.
