I am re-torquing my keel bolt nuts to deal with a little "Catalina smile issue. I bought the deep socket and the ten inch extension then went looking for a torque wrench. To my suprise, I found that the "Auto Zone" chain of auto parts stores lends them out. You give them $100 on a credit card and then when you bring it back, you get the money back. They let you keep it for up to three months, and it's a great wrench! I asked them how they make their money and they said, "you may buy parts from us in the future." Wow! I may. All the best, Jerry
