Correct 5X4 Cragar SS 7/16 Lug Nut Torque?

The washers have always been crap! Years ago I worked in a machine shop and made some 1/8" thick Cragar washers out of hardened stainless steel. They worked great. Sad thing is, there is no "standard" washer that will work. Believe me, I looked everywhere. Recently, I saw that McGard makes nuts with s/s washers for Cragars. Did not check on the exact sizes made though. I think if you check your shank size and washer size, they might be shown here: http://www.summitracing.com/search/part-type/lug-nuts/lug-nut-seat-style/shank/washer-included/yes?N=4294947616%2B400067%2B4294947603%2B4294920298%2B4294947790&SortBy=Default&SortOrder=Ascending&tw=lug%20nut&sw=Lug%20Nuts
