Lineman's buddy!
Great socket for linemen. Popped it on a M18 mid torque 1/2 impact and it's never left. It's become my go to socket for day to day distribution line work. Great for shoes, hotline clamps, cutout arms, you name it. Doesn't replace the nut runners or anything used on the 7/16 M18 Utility impact, but works great on a smaller, lighter impact for tasks that require more dexterity. Can't speak about long term durability. It's been in use on my truck for about 3 months with daily mild to moderate use.

Great buy and comes in handy to have!
Inside spring gets stuck so have to play with it sometimes in order to use on smaller bolts but great to have!

Bought this for use in powerline construction, fits 99.9% of the smaller nuts…there’s the odd 1/2” out there but not common enough to buy the socket kit
