Pneumatic Wrench

Grease covered casual khakis account for the labor spent loosening and tightening all of the little and large nuts and bolts needing to be wrench off and on and all around your automobile. Wrenches have existed for many centuries, but saw a great blossoming of development starting in the nineteenth century. The first patent for a wrench was granted in 1835 to Solymon Merrick. This tool has multiplication ratios up to 4000:1 and is primarily used anywhere accurate torque is required on a nut and bolt, or where a stubborn nut needs to be removed. These wrenches have very little vibration, and excellent repeatability and accuracy. This sound uses the following file from Freesound: http://www.freesound.org/samplesViewSingle.php?id=91910
