We love weekend fix-it projects but don"t like making trips to the hardware/home improvement store for those 1 or 2 critical fasteners - they waste gas and valuable time, so here"s a better idea: set up your own mini hardware store with 1,200 of the most commonly-used nuts, bolts, washers and screws. This great kit has both SAE/standard/Imperial AND metric sizes - and all the screws and bolts are Phillips-head (preferred by most handymen). Slide-out organizer cases have triple-latch tops with movable compartments to keep sizes/types easy to find. Sturdy steel rack sits on your work bench and has a grab--go handle or wall-mount to save space. All pieces are galvanized steel for superior rust resistance indoors and out. SAE nut/bolt/washer sizes #6, 8, 10 and 1/4" in 4 lengths metric M3, 4, 5 6. 12 sizes of wood/sheet metal screws in #6, 8, 10 plus bonus 12-compartment organizer case for those extra hardware pieces. Overall dimensions 12"W x 9"H x 6"D 4 lbs.
