Dowel pins are precision-engineered components used to align or join two parts, often in machinery, automotive assembly, furniture, and construction. These cylindrical pins ensure accurate positioning, providing a high level of structural stability. Dowel pins come in a variety of materials, such as hardened steel, stainless steel, depending on the required load-bearing capacity and environmental conditions.They are also corrosion-resistant, ensuring long-term durability, especially in outdoor or high-humidity environments.
