These nails were great for use with a framed nailing tool (although I did hand hammer some in tricky spots) for a large fencing project. We had to attach standard cedar picket fence posts to finished 4x4 fence posts and finding the right nails for this wood combination took some research. These nails were recommended and have worked very well. They will not discolor the pickets over time, and the ring bars should minimize their movement during Michigan thermal thaw cycles. Very satisfied.
