What is the preferred material for dowels in construction?

The preferred material for dowels in construction is hardwood due to its strength and durability. Hardwood dowels provide long-lasting support in various applications, such as furniture making and cabinetry. The density of hardwood means that it can properly hold screws and other fasteners without easily splitting or breaking, which is essential for maintaining the integrity of a construction project.

Additionally, hardwood dowels tend to have a tighter grain structure that reduces the likelihood of warping or expanding when exposed to moisture, ensuring a more stable finished product over time. This resilience makes hardwood a preferred choice over softer materials, which might not withstand the same stresses and could lead to weaker joints or connections. In contrast to plywood or metal, which serve different roles in construction, hardwood dowels are specifically preferred for applications that require reliable connecting pins or supports.
