Stainless Steel Double-Flange Locating Pin, 304 Precision Dowel Pin, Custom Mechanical Alignment Post, Factory Direct Supply

A shaft component designed for precise positioning in mechanical modules or through-panel mounting. It features a symmetrical structure with disc flanges at both ends and a slender cylindrical rod in the middle. This double-headed design provides axial限位 references in two directions, while the smooth central shaft serves as a guide or insertion fit. It is commonly used in tooling fixtures for automation equipment, mold guide pillars, and internal instrument support, ensuring coaxiality and connection rigidity after assembly.

The manufacturing process leverages the high-precision rotational machining capabilities of CNC lathes, strictly controlling the perpendicularity of the flange faces relative to the central axis and the straightness of the long rod to prevent wobble or jamming after assembly. For slender rod structures, cutting parameters are optimized to suppress machining deformation. Fine deburring is performed on flange edges and the rod body to remove sharp edges and ensure operational safety. For tight clearance fits, outer diameter tolerances are strictly controlled to ensure smooth insertion and removal without looseness.

Equipped with multiple high-precision CNC lathes and Coordinate Measuring Machines (CMM), we support non-standard customization of materials (such as 304/316L stainless steel, carbon steel), flange diameter, and rod length based on 2D/3D drawings. Adhering to the ISO 9001 quality management system, our production process covers material traceability, go/no-go gauge inspection of critical dimensions, and 100% visual inspection. We provide material certificates and inspection reports to ensure that batch-delivered products meet the stringent standards of mechanical manufacturing, semiconductor equipment, and high-end automated production lines in terms of fitting precision and consistency.
