Timber bolts, also known as dome head bolts or mushroom head bolts, are specialized fasteners designed for heavy timber and wooden structural applications. These bolts play a crucial role in connecting wooden beams, columns, and other load-bearing elements securely. Unlike traditional hex bolts, timber bolts feature a large, rounded head with a built-in washer-like flange that prevents the bolt from pulling through the wood. This design distributes load pressure evenly across the timber surface, reducing the risk of splitting or localized damage.
