Abstract
In order to stabilize a timber bolt joint against coming loose when the timber shrinks the bolt hole in the timber element is made with oversize and a bushing of Nylon is inserted with tight fit in the hole, the bushing having substantially the same length as the hole. When the bolt nut is tightened it is primarily the bushing, which is clamped, and thereafter the stability of the joint will be safeguarded even if or when the timber shrinks.
