Used this on multiple semi lug nuts and various other equipment with tight rusted bolts. Pleased with its performance wish I would have bought one earlier.
I used this tool to crack crank pulley bolt 2007 Honda Odyssey with a couple reduce to 1/2 in 19 mm socket and crank shaft holder like a stopper . Works very good no need 3/4 impact air gun . On Isuzu wheel nut crack open easy
