DIN6915 is a heavy hexagon nut for high-strength structural bolt assemblies. It is widely used in steel construction projects, matched with DIN6914 bolts. Made of carbon steel, it features high mechanical strength and reliable anti-loading performance. Available in various surface treatments like black oxide, zinc plating. Strictly sized to DIN standard, it ensures stable connection for steel frames and bridges.

DIN6915 heavy hex structural nuts are originally developed for European steel construction, so Western Europe remains its core market, including Germany, France, UK, Spain and Italy. These products are widely adopted for steel bridges, industrial steel buildings, power transmission towers and wind farm projects that follow EN 14399 structural fastener specifications. Eastern Europe is another fast-growing region with rising demand for infrastructure renovation and new construction projects.

The Middle East is an important export destination. Large-scale oil & gas facilities, high-rise steel structures and coastal infrastructure require hot-dip galvanized DIN6915 nuts for corrosion resistance. Southeast Asia and Oceania also consume large volumes for bridge, solar and industrial plant builds. Besides, some customers in South Asia and Latin America select DIN6915 for European-standard EPC projects.

Domestically in China, it serves domestic steel structure, wind power and railway projects, and supports Chinese overseas engineering contractors. Buyers prioritize certified 10-grade HV nuts with 3.1 material test certificates, various surface treatments including black finish, zinc plating and HDG to fit different environmental requirements.

Established in 2005, our company has evolved over two decades of continuous development into a leading regional enterprise in the fastener industry with fully automated end-to-end production. With an annual output value exceeding RMB 130 million, our product range covers diverse market segments from mid-range to high-end and is distributed worldwide
