How often do Thru-Bolts need to be tightened?
There is no preset schedule to actually tighten the Thru-Bolts, but they should be checked periodically for the first few years to ensure that they remain tight. After the house has settled, usually after 3 or 4 years, they should be checked every couple of years. The nuts can be reached in the attic, basement, or crawl space, depending on the setup of the house. It should be remembered that these are auxiliary devices that help the logs to seal together. The weight of the logs themselves are the primary source of compression. The Thru-Bolts do not need to be tightened down with any hopped-up mechanical device. A simple wrench and the power you can put behind it are sufficient. We do offer self-tightening Thru-Bolts as well. Few opt for these.
