Dont buy tectonic brand. Their a lessor alloy blend of metal and thinner that in comparison this will loosen the stubborn nut better. Due to this socket will transfer the energy blasting a counterclockwise rotation verse uselessly wasting the loosening energy by the gun into tinny rattles of thin crappy metal spcket walls I also think the larger size of 3/4 mass leads to better action vs. 1/2 socket. Example. Would you use a big hammer or little hammer to jar somwthing?
