Improvements Craft Storage Cart

After reading the reviews, I was hesitant to buy this product. Thank goodness I bought two on sale. The screws work fine as they should. Apply pression against the side of the cart and the side where you have to screw the bolts. Attach the bolts on opposites sides (X), I assembled them myself. Hold the bolt with the to keep it still and adjust the screw with the L tool. I cannot believe I had a great size rolling and wall system for this price. I am so happy with this product.
