  • Technique for fastening logs and fastener therefor
    Patent number: 5400845
    Abstract: A technique for fastening together logs and a fastener therefor is directed to a self-drilling/tapping fastener which allows the fastener to be driven through the log to be secured without pre-drilling a bore. Counter-bore fins on the fastener head also form a counter-bore for the head. A lubricious coating applied to a portion of the shank accommodates settling of the logs and facilitates installation.
