Hillman 42482 #9 x 3 in. Outdoor Wood Screw, 50-Pack

these are pretty nice in concept and in practice. They have an extra bit of twist at the top of the screw that seems to keep the wood from splitting when you tighten down the last bit. They also have a sort of serration at the tip that keeps you from having to use a pre-drilled hole. This also seems to keep the wood from splitting when driven with no pre-drilled hole. The package even came with a nice star bit to drive them with. I like star screws the most because they are easier to drive without stripping the heads.

We used these for hurricane prepping. We used them to attach two pieces of plywood together. The attachment between to two pieces of wood were very strong. The screws come neatly packed in a resealable plastic container. Great strong screws for the exterior. I highly recommend. [This review was collected as part of a promotion.]
