Jiaxing City Qunbang Hardware Co., Ltd Cases

     In March 2019, our company visited BOSSARD in France after attending the fastener exhibition in Stuttgart, Germany. We were warmly received by the leaders of the company. They introduced BOSSARD's development history, management mode, procurement mode, inspection mode and so on to us. And we visited the company's automated storage, laboratory, office area, sample area and so on. Which lefted us a very deep impact.          We believe that we can bring our company a qualitative leap through the cooperation with the top European fastener enterprises. Not only in the quality of sublimation, but also in the management mode.           Project Name：DIN931 CLASS 6.8  Cr3+ Size:M8X58 Quantity: 2 containers Marking:QBH 6.8 Drawing:                    

Since 2016, we have successively provided DIN557 hot-dip galvanized square nuts for Bangladesh Army factories, which are mainly used in power system. In 2017, we were honored to visit the customer's factory, which laid a solid foundation for future cooperation.   Metric DIN 557 regular pattern square nuts are four sided nuts. Their geometry provides a greater surface area to apply higher torque when tightening and also a greater surface are in contact with the part being fastened, thereby increasing the resistance to loosening.
