I've generally bought wood screws at the big box stores (HD, Lowes). However, I think these screws, Grip-Rite, other brands I can't recall, are not the highest quality. After I had two 3" screws break off when I was trying to attach a SYP fence to a crosscut sled (yes, I had pilot holes but they could have been undersized), I decided I might need to start buying better quality screws. Just wondering where everyone buys there wood screws from? Of course, we all want the best quality at the lowest price. Thanks!
