This is a copy of the reply to soloboy's pm:

6907D is the model number. It is 9.6 volt 3/8 inch drive. Sorry but it won't come anywhere near breaking a lug nut. It is made for light duty stuff. I usually use it for interior stuff, and little under the hood stuff(spark plugs if they were installed and torqued properly). So no lug nuts or suspension stuff. It is rated at 50 ft.lbs if that gives you an idea.
