Review on Efficiently Remove Drain Plugs with CTA Tools 2049 Square Head Socket Set - 2 Pieces by Philip Breeze

One of the included drain plugs is needed to drain the transfer case oil from my Nissan Versa manual transmission. Nissan opted for a square-headed drain plug, presumably to discourage people from messing with the transmission. A 3/8" ratchet or 1/2" ratchet will not work with these drain plugs. These drain fittings were cheap and did the job. Feel solid. I hope they never have to test their powers in the future.
