New Snap-On 3/8-Inch Magnesium Impact Wrench Offers Increased Versatility in a Lighter Weight, More Powerful Package

KENOSHA, Wis., May 9, 2005 - Continuing Snap-on Tools Company's dedication to innovation in design and performance, the Snap-on® 3/8-inch Magnesium Impact Wrench (MG31) places impervious structure, reduced weight and improved torque into the hands of vehicle technicians and enthusiasts. The new tool helps users tackle on-the-spot jobs such as removing lug nuts, loosening tie rod ends and securing other fasteners more accurately, quickly and comfortably than ever before. The Snap-on Magnesium Impact Wrench combines the strength and reduced weight of magnesium with Snap-on's patented one-piece housing design to provide increased performance and comfort. At 2.9 pounds, the tool's balanced design, cushioned trigger and low vibration motor ensure control for jobs that require extended operation in a variety of working positions, including under-car and above-shoulder tasks. Enhancing the tool's applicability, a slim nose design allows greater access to restricted areas. The tool's features combine to reduce operator fatigue, making the MG31 a primary choice for technicians, repair shops and industry - from alignment technicians, muffler shops, manufacturing facilities and salvage yards - who use impact wrenches as their most important tool. An internal twin hammer mechanism delivers increased impact per blow at 300 foot-pounds of torque, an ample amount of force for nearly any tightening or loosening job. The reverse bias motor offers extra torque to quickly remove stubborn, stuck or rusted-on fasteners. The motor's eight-vane rotor increases anvil acceleration and allows consistent performance when working in low and high compressed air environments. Snap-on uses Red Line Synthetic Racing Oil to continuously lubricate critical and fast-moving internal components further protecting and prolonging the life of the Snap-on Magnesium Impact Wrench. Constant lubrication maintains the integrity of the air hammer's motor, reducing potential maintenance downtime and protecting the owner's investment. The permanent, maintenance-free oil bath minimizes the extra effort of greasing components on traditional impact wrenches and helps extend the overall life of the tool. An Anvil Stop Lock feature immediately halts the spinning anvil upon trigger release, which increases safety by preventing bolts or sockets from slipping or suddenly releasing. Additional features that enhance the Snap-on Magnesium Impact Wrench are a replaceable non-slip, comfort-cushioned handle and trigger, shielding the users hand from cold, compressed air and adding comfort during use. The cushioned material helps reduce user fatigue and increase user control. Metal reverse and power controls add greater durability and longer life to the tool-a distinct feature on all new Snap-on impact wrenches. The Snap-on Magnesium Impact Wrench is designed for tightening and removal tasks in an array of work environments, including motorcycle, automotive, ATV, truck, boating, small engine and tire shops, as well as home garages.
