Im a hot side and cold side equipment tech(restaurants). im looking for a decent set of 6pt 1/4" and 3/8" socket sets, they wont get used much, most of the stuff i work on i use nut divers and screw drivers but want a set in the van for when i need them. i have probably every socket craftsman makes at home but those will stay at home. they may get lost by helpers and other techs but still need to hold up and have a lifetime warranty. i was looking at husky and kobalt, but honestly hf look the same quality, which isnt bad but hf is cheaper. how are the hf extensions and sockets?
