    Winch hook up
  

*by T***E on Reviewed in the United States on April 18, 2023*

Used this on my truck to put power to winch motor. Fastened it to the positive post on the battery, worked as it should, put 12000 lb winch on 2 gage wire used it a couple times check to see if it go hot didn't even get warm. Works great.

    Strange Combo of US and Metric
  

*by A***R on Reviewed in the United States on February 2, 2023*

Despite what some of the answers to questions say above, the female thread on the brass coupler is 5/16 inch and fits the threaded vertical top terminals on the eight new Trojan T105 6 volt batteries I just installed in my motorhome,  The male stud on the brass coupler is also 5/16 inch thread,  However, the wrench flats on the brass coupler and the nut are metric,  A very strange combination,  Works okay to enable the stacked connection of  the multiple cables I have going to each battery terminal,  Price is excessive,

    Works like a brass bolt and nut should
  

*by M***R on Reviewed in the United States on February 3, 2023*

I ordered two.  Thy fit snugly into the dreaded GM side terminals providing a better contact than the flimsy OEM connectors.  An added benefit is being able to attach accessories, and not have to use little vice grips to test or charge the battery.
