Are the manual impact drivers which you whack with a hammer any use at all with anything but screws and small sockets? For example I need to shift a moderately rusty 15mm bolt which won't budge, on solid, flat bodywork - would one have any chance of helping? Some have a 1/2" drive so it sounds like maybe they can be reasonably beefy. It doesn't need to be fast and I'm aware it's not going to beat a powered driver.

I have one of these and I don't recall that it ever worked for me.
These days the cost of an electric impact wrench is so low that I wouldn't fool with one of these.

1Worked well for me, but back in the day when rechargeable impact wrenches did not exist. Also had the strength to hit it hard enough... Jul 13, 2021 at 2:58

1I agree with Solar Mike. They work fine so long as you have a heavy hammer, and the confidence to use it without breaking the fingers holding the driver (whether they are your own fingers or someone else's!). Tapping them gently with a 1 pound (500g) hammer is a complete waste of time. Jul 13, 2021 at 4:10

1This is one of those tools that requires practice to use, if you use it regularly it's fine, if you don't it's a source of frustration.– GdDJul 13, 2021 at 8:43

1I find them most handy for screws. Like the screws that are stuck on brake rotors.– JupiterJul 13, 2021 at 15:53
