適用范圍：This part of ISO 5855 specifies the general requirements for MJ threads used in aerospace construction.It determines the basic triangular profile for this type of thread and gives a system for designating the diameterand pitch combinations. For all diameters 1,6 mm to 300 mm, it offers in the form of tables the basicdimensions and tolerances for a selection of diameter and pitch combinations. It also provides the method ofcalculation for the dimensions and tolerances for any diameter and pitch combination not given in the tables,including threads with a diameter in excess of 300 mm.For limit dimensions for bolts and nuts of nominal diameter 1,6 mm to 39 mm, see ISO 5855-2. For limitdimensions for fittings for fluid systems, see ISO 5855-3.
