Underneath a car, not really. If it was reverse biased (as many impact wrenches are), that makes it much more useful in removing things, but there's no way an impact driver would be reverse biased as it's designed use is in the forward direction. Small bolts under the hood or in the dash board, sure, not not in a wheel well.
So it comes with adapters that allow you to use it with hex head screws/lag screws. So what?
Impact drivers are an indispensable construction tool. They are not a mechanic's tool.
you remember saying that right? why the change of heart?
also, how come a 1/4" square drive pneumatic rated at 25 ft/lbs is better suited for under a wheel well, but the hex driver with 133 ft/lbs isnt?
why would a 3/8ths electric impact rated at 180 be better than a hex driver with 3/8th attachment when working in a wheel well?
real questions here, just want to get a gauge on where you seem to think the torque from 6 sided adapter is different than the torque from a 4 sided adapter.
i'd like to add that i wonder where the idea that if it doesn't have a breakaway torque vs fastening torque listed, it means it isn't meant to be used under a car.
how come anything with 3/8th drive or lower pneumatic impact wrenches don't show what their two ratings are on snap-ons website? are we to assume that only 1/2" impacts are to be used under a car and the 3/8ths impact are meant for light duty like interior, m4-m8 nuts and bolts and thats it? what i gather from your complaint is that the aforementioned hex driver is not meant for nuts and bolts because it does not have a stronger reverse than a forward. can the same be said about these impact guns with only one rating?
