I was doing some deck repairs/rebuilding and needed some 5” screws to secure the structural supports. These screws were available for about half of what the orange home improvement store wanted. These are well made and worked great. The included bit fits the heads well. This is a large box, and I really like that they shipped them in cardboard rather than some clear plastic case that will break in transit. The cardboard is easier to recycle than the plastic where I live.
