The counterbore of nuts with thread diameter equal to or greater than 4 mm is deep enough toaccommodate a bolt shank in excess of assembly thickness, as well as the incomplete threadsThe 3 mm diameter nut has no counterbore.They are intended to be used with threaded parts of 1 100 MPa 1) tensile strength classification.The cadmium plating restricts the application to temperatures not exceeding 235 ℃.【中国标准分类号】: V20【国际标准分类号】: 49_030_30【页数】: 18P.;A4【正文语种】:
