    Shanghai Jian & Mei Industry and Trade Co., Ltd. Customer Reviews

    My name is Mike.I am a fastener wholesaler from Mexico.I remember clearly when we find Shanghai J&M first time is from google. Our first order is A193 B7 stud bolt and A194 Grade.2H nuts, the value is not big ,just as a trial order. When we received the goods , tidy and strong package , complete and professional test report made a good impression on me. After each items were all passed the test in our own lab,and each target is much higher than the standard specification, our company is very satisfied with JM products. Since we have a bad experience ,purchase the same stud bolts and nuts in China with a little low price.When got the products, many of them were not meet the standard. So from that time, our company began to purchased bolts ,nuts and washers from JM largely. Now it is more than three yeas. It is very lucky to find shanghai J&M at that time, makes my purchase work become more high-efficient and convenient and relieved .
