The Lang Tools Universal 6-in-1 Fan Clutch Wrench combines the six most commonly used wrench sizes into one double-ended wrench. The offset design provides better hand alignment and a clear line of sight, while improving accessibility in tight fan clutch areas. Two square drives allow for use with a breaker bar for added torque or length. Sizes included are 22mm, 23mm, 36mm, 40mm, 48mm and 50mm. This patented tool is designed, engineered and manufactured in the USA.
