The AME Nut Buddy is designed to loosen stuck stubborn or seized lug nuts on hub piloted wheel assemblies. Put away the torch and quit replacing or damaging studs. The AME Nut Buddy reaction arm rests against an adjacent nut while the handle is fitted over the back drive. Utilize the 58 to 1 Gear Ratio to break loose the stuck nut. Turning the handle is effortless and the feeling of breaking loose a nut that an impact cheater bar or large wrench couldn t is extremely satisfying. Not to mention the burden lifted once you realize you don t have to break out the torch to remove the nut. The AME Nut Buddy ships with two 1 Inch sockets; 33mm and 38mm which cover the majority of the wheel assemblies on the road today. It also fits any standard one inch drive socket should you encounter an irregular nut size. It can be used on Left Hand and Right Hand threads as well. An additional manual handle is also included to use once the nut is loosened just in case you don t have an impact nearby or you re on a roadside service call.
