We do not typically use a “thru-bolt” system in our log homes. We generally use Olympic Log Hog screws in our log homes. This system is generally much less complicated and expensive to assemble. Thru-bolts are generally reserved for log homes that are built using wood with a high moisture content. Generally the first course of logs is bolted to the foundation and the Log Hog screws are used from there up throughout the log wall. The result is the logs are fastened together throughout the wall, not at specific hold-down points.
