anyone having trouble with premature wear out of kleins 1/4 inch nut drivers specifically the 646-1/4 model ? my klein rep is being stubborn over the warranty.

dont know what they are making the small furnace cabinet screws out of anymore but they sure round off the inside of the hex fast.

have noticed also the quality with craftsman running down hill. the nut drivers used to be a lot thicker where the hex is. some of my old professional series stuff has been discontinued. so now it sits in the workshop at home. dont wanna bust it.
