                        Haixin® Flange nuts have a wide flange at one end that acts as an integrated, not-spinning washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. Hex flange nuts have become more and more popular in wind energy field. Many wind turbine customers have changed common HV hex nuts to hex flange nuts. This is a trend, because hex flange nuts have better and safer performance.

                        Our factory strictly carries out every test of the flange nuts. Testings including dimensions, gauges, decarburization, 90% martensite, MPI, hardness, proofload, run out, marks and finish are carried out on every batch. So the quality can be fully guaranteed. The flange nuts have been well accepted by wind power giants and widely exported to Germany, Denmark, Norway, Spain, Great Britain, Poland, India, etc.
