Product Description
Introduction
Dowel Pins are precision cylindrical components used for accurate alignment, positioning, and fixing of parts in mechanical assemblies, molds, and tooling systems. They ensure repeatable fit between components, improving structural stability and assembly accuracy. Manufactured from alloy steel, stainless steel, or hardened tool steel, they are designed for demanding industrial environments where precision and reliability are essential.
Produced through advanced CNC machining, grinding, and heat treatment processes, Dowel Pins achieve high dimensional accuracy with tight tolerances up to ±0.002 mm. Depending on material selection, hardness can reach HRC 58–62, providing strong resistance to wear and deformation. Their smooth surface finish ensures easy insertion and stable fit, reducing assembly errors and improving operational efficiency in production lines.
Dowel Pins are widely used in automotive manufacturing, precision machinery, mold and die systems, fixtures, jigs, and industrial automation equipment. They are essential in applications requiring precise alignment and repeatable positioning. Custom options such as diameter, length, tolerance class, material grade, and surface finish are available to meet specific engineering requirements, making them a flexible and reliable solution for OEM and industrial assembly applications.
