ABSTRACT:
A fastener for fastening together logs and a technique 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 wings on shaft segment of the fastener shank increase the diameter of the bore formed in the log to be fastened by the threaded segment of the shank, reducing friction caused by contact between the shaft segment and the bore. Counter-bore fins on the fastener head also form a counter-bore for the head. A lubricous coating applied to a portion of the shank accommodates settling of the logs and facilitates installation.
