150 ft/lbs is more than most automotive fasteners require. Most wrenches that are accurate up to 150 ft/lbs do not go down to 15-20 ft/lbs. Minimum on most that I am familiar with go from 50-150 ft/lbs. That is one of my responsibilities at work is to check calibration on about 300 wrenches monthly. Can anyone chime in on the torque spec for wheels? Alot of manufacturers are around 85-100 ft/lbs. Surely that is more than anyone would want if they need a wrench for such items as oil drain plugs. With that being said...I believe for DIY purposes, I would have two wrenches....one for the low end of the spectrum and one for higher end torque values. That is, if you are needing something to torque items such as suspension components.
