| Thought some of you might be interested in this. After stripping a couple transmission drain plugs using a 1/2" drive I started looking for the right tool for the job. [ http://ultimatetoolco.com/drainplugs.aspx ] Not cheap but no more worries. Also found some 13mm square drives on ebay auctions in Great Britain for cheaper. Odd that I couldn't find this from any major tool manufacturer or retailer here in the states.
