    Thread is wrong
  

*by S***N on Reviewed in the United States on October 28, 2023*

Be advised the thread size for the terminal bolt is wrong. You can use the supplied bolt IF/ you can get the original one out. Most are captured to prevent loss. I was careful and used anti seize on the existing bolt the basically rethread it but you risk stripping it.Also, it shoud come with lock washers particularly on the battery terminal see. That bolt is correct threadThat said, it works well as a disconnect
