Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railroad hardware and wire mesh products. With annual export value exceeding US$5 million and serving markets across North America, South America, Europe, Asia, and Africa, we bring over two decades of manufacturing expertise to every product. Our Dowel Pin for Railroad Tie Repair (5/8 inch diameter, 8 inch length) is engineered to provide reliable fastening and structural integrity in railway construction and maintenance. It is a cost-effective solution for securing loose or damaged railroad ties, ensuring long-term track stability and safety.
This dowel pin is precision-manufactured from high-quality carbon steel, offering excellent strength and durability.
