I don't know the name of the tool, but I think I know what you're talking about. They are like small sockets with internal splines that are angled to grip the remains of a bolt. The shaft of the tool is hex-shaped to chuck very securely into a reversible drill. I bought a set at Sears, and they worked for me in the past. -Joe Kuchan >From: Woody <BePositive2000@xxxxxxxxx> >Reply-To: dmcnews@xxxxxxxxxxxxxxx >To: dmcnews@xxxxxxxxxxxxxxx >Subject: Re: [DML] Broken Head Bolt advice >Date: Tue, 31 May 2005 11:16:00 -0700 (PDT) > >Jeff, > >Recently I saw a head bolt removed with a tool that looks like a nut >with left handed, tapered threads.
