  • Distro linemen have wet dreams about these
Size: 3/4-Inch and 9/16-Inch Spring Loaded Socket
I've had a combo socket 9/16-3/4 and a slot socket for a few years now but this socket takes it up a notch. The Klein 3in1 9/16-3/4-slot socket is a dream for distribution work. Just keep this on your small impact and you won't have to change sockets or fumble with manual tools in rubber gloves nearly as as often. I'm cheap so I know the price seems steep but if you can only afford 1 socket get this one. You only have 1 set of hands so buy this and try to save them (rubber gloves and carpal tunnel are inevitable). I know this is a glowing review and all but if you use this socket hard for 9-12 months expect to replace it as it will wear/spread and bind up much faster than combo sockets without the slot. *Side note if you don't use hot taps or "coily macks" forgo the 3in1 socket and just get a combo socket as it will last longer. Good luck and be safe out there! ... show more
