Frequently asked questions about hard and ground dowel pins What are hardened and ground dowel pins used for? The dowel pins are used to accurately locate and align machine components, tooling, fixtures, and mechanical assemblies where accurate positioning is critical. What does DIN 6325 mean? DIN 6325 is a recognised engineering standard for precision hardened and ground parallel dowel pins used in mechanical assemblies. Do dowel pins need reamed holes? Yes, in most precision engineering applications, dowel pins are designed to fit into drilled and reamed holes for correct tolerance and alignment. What hardness are hardened dowel pins? DIN 6325 dowel pins are typically through hardened to approximately 60 ±2 HRC, providing excellent wear resistance. Can hardened dowel pins be reused? In many applications, yes, provided there is no wear, damage, or deformation during removal or operation.
