I know this IS the wrong section but maybe the best section to ask. Ive lost/mislaid/packed away one of those little Presto Tools cards with the sizes and threads per inch of screws and bolts. The one I have/had has BSW,BSF,UNC,UNF, BA etc on it. I dont suppose one of you engineer types can send me one? It was slightly smaller than a plating card. It doesn,t have to be a Presto one but they are handy. Damn---Brain like a wotsit these days. Thanks ggggr
