Overview
ISO 8734 is a dimensional standard for hardened and ground cylindrical dowel pins used in industrial, mechanical, and engineering assemblies. It defines key dimensional characteristics, tolerances, and fit requirements to support alignment accuracy and assembly consistency. The standard is commonly referenced together with material, hardness, and inspection standards depending on the application requirements. ISO 8734 dowel pins are commonly available in carbon steel, stainless steel, alloy steel, and corrosion-resistant finishes. When sourcing ISO 8734 dowel pins, the standard alone may not fully define the product requirements. Additional specifications may include hardness requirements, tolerance class, surface finish, and certification requirements.
