The wrenches work fine but not until I ground the bolt end for clearance around the bolt head.

Simple, no-nonsense product. We did have to grind the socket end down to make both the socket height and thickness smaller in order to fit on our Cessna 150s cylinder nuts, but that wasnt too difficult.

CYL BASE NUT WRENCH 5/8 HEX

April 22, 2022

This wrench did not even begin to fit on a cylinder base nut, as received. I spent quite some time grinding and filing it down to be able to make it fit over the cylinder base nut, and clear the last cylinder barrel fins, and the cylinder barrel. It was the same case with the last wrench I bought 35 years ago so I wasnt surprised.
