Standard dowel pin is a high-precision positioning fastener with a solid cylindrical structure, mainly used for positioning, centering and connection of mechanical components. It is widely applied in various fields such as general machinery, automobile manufacturing, mold tooling and precision instruments. The product strictly complies with international and domestic industry standards including ISO8734, DIN6325 and GB/T119, with materials mainly covering carbon steel, stainless steel, alloy steel, etc., which can be flexibly selected according to the use scenario. As a core positioning component, the standard dowel pin has the core advantages of high precision tolerance (conventional h6/h7/m6 grade), high shear strength and wear resistance. The surface can be treated with zinc plating, black oxide, polishing, etc., to adapt to different working conditions. Whether it is the micron-level positioning of precision equipment or the basic centering of general machinery, the standard dowel pin can ensure accurate component assembly and reliable operation with its stable performance. At the same time, it supports customized sizes (diameter 1-50mm, length 6-200mm) to meet the personalized needs of different customers, and is an indispensable basic fastener in industrial production.
