Over the last couple of years I have worn out a couple of nut drivers that I use for washer and dryer repairs. I use these to take the small hex head screws out and replace them that are common on Maytag, Whirlpool, etc. The ones I have worn out most frequently are the 5/16 and 1/4" sizes . The ends of these can be ground off slightly to provide a non worn engagement area for the hex of the screws and it works for an additional couple of months. The material is not a hardened steel so it wears out more quickly than I like. This week my local Menards store had a really good sale on tools so I bought some items that hopefully will last longer . Specifically I purchased a Masterforce spinner handle which is item number 10815 which accepts 1/4" drive sockets . I also bought the 1/4" drive sockets for the 1/4" and the 5/16" size hex screws. Hopefully these will last longer but when they do wear out I can replace the socket separately and get much more use out of this item. I should have done this a long time ago.
