Sunex master set sweet!
Gray and Gear wrench brands have smaller sets too
I have debated getting an inclusive 1/4" drive impact set so I'm following along here
But are you talking for use with 1/4 hex drive impact tools?
I mainly use 3/8 impact sockets with a 3/8 x 1/4"adapter on those. I have several length adapters up 12 inch to use too.
But have used some reg. shallow craftsman on 1/4 X 1/4 shank not what I like to do but seen no ill effects either. I just don't really know how much power someone intends to apply to these smaller sockets
Makita has very small SAE socket set with adapter and holder they market for impact drivers and most tool brands usually have some sort of small impact rated set with their name on them.
I do have an 8 pc set of no name Taiwan stamped SAE 1/4" deep impacts came from somewhere maybe Cal Hawk Brand dunno that I use and not the greatest but also the reg. depth Craftsman 1/4" have been on the 2452 FUEL (rated 500 in lb/42 ft. lbs. max) with no problem. Just a note about that someone had a few cheapie no name sockets and the first one they used actually twisted and deformed on the anvil and I needed a pair of pliers to work it off. They were total **** lol.
And pretty much half inch is like max size with most common 1/4 drives sets anyhow right?
As for nut runners I have tried a few. The cheap Tekton's I have issues with and a few of them just wont lock in ANY of my Milwaukee 1/4 shank drivers. The shank portion is just too short.
I have the Neiko impact set Sae/Metric 1/4-9/16 & 8-14mm magnetic nutdrivers. A decent set with all the slightly larger sizes but they are shallow and magnets can be easily be shattered pounding up to full power. Their 5 pc sets SAE or Metric are ok too.
Titan makes some hollow core nutdrivers up to 9/16 and 14mm but never could get past the shipping charges trying to source them.
And on Amazon there is VIM set with decent reviews that has both shallow and deep nutsetters in one set. But come only SAE or Metric per set. Could buy some full socket sets for around the same money
