Good product, good price

I do a lot of design and prototype work, and no 2 jobs need the same range of bolts, screws and nuts, and a lot of them aren't available at local hardware stores. FMW has a wide variety of cap screws and bolts in lengths that just can't be found elsewhere. Being able to buy in quantities of 1, 2, a dozen, or a box full makes my job a lot easier. The price per piece is an exceptionally good deal, and the low shipping costs will keep me coming back for more.
