Similarly, do I need deep sockets? In this case, a deep socket is necessary to accommodate the long end of the bolt and fit snugly around the nut. Having some deep sockets on hand can be helpful for situations like this. Without them, you may need a wrench instead of a socket to loosen that nut.
Likewise, what's the difference between impact sockets and regular sockets?
To my knowledge the difference is down to the material used The surface-hardening enables impact sockets to absorb sudden torque changes (aka "impact") better. With high enough impact, a regular socket may warp out of shape because the steel used there is softer.
Can impact sockets be used as regular sockets?
The short answer is yes, with some minor caveats. Depending on what you're wrenching on, an impact socket can be used in place of a normal socket when using a normal (non-impact) ratchet. Similarly, it is safe to use an impact socket on a hand ratchet (although not vice versa).

Can You Use a Cordless Impact Driver to Remove Lug Nuts? The short answer is yes, but it depends.

I recommend staying near the middle in terms of size. So, go for either a 3/8-inch impact wrench or even better, a 1/2-inch impact wrench.

Check the thread size for a lug nut. Refer to the vehicle owner's manual for thread dimensions; measure the width of threads on the lug bolt with measuring tape, or bring the nut to a hardware store and twist it around the thread pitch gauge or compare it to loose bolts with marked sizes.How do I know what size nut I have?
Stretch the tape measure across the nut's diameter to the flat-side directly across from the one your pulling from. If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut.Should I get shallow or deep impact sockets?
Shallow are good for smaller bolts and where you need clearance, but deep sockets are saviors for those hard-to-reach bolts and will let you get a better grip on nuts threaded far down a blind bolt/stud.Can I use regular sockets with an air ratchet?
