                        Product Description

                        Collar nuts are a kind of flange nuts. Collar 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. Collar nuts have become more and more popular in the wind energy field. Many wind turbine customers have changed common HV hex nuts to collar nuts. This is a trend, because collar nuts have better and safer performance.
