    Abstract - (Show below) - (Hide below)

    Defines requirements for MJ threads used in aerospace construction, determining the basic triangle profile for this type of thread giving a system for designating the diameter and pitch combinations. For diameters ranging from 1.6 mm to 300 mm, it offers the basic dimensions and tolerances in forms of tables for a selection of pitch and diameter combinations. Covers the method of calculation for the dimensions and tolerances for any combination not given in the tables, including threads with a diameter in excess of 300 mm. For limit dimensions for nuts and bolts of nominal diameter 1.6 mm to 39 mm, see ISO 5855-2. For limit dimensions for fittings for fluid systems, see ISO 4744-3.

    Scope - (Show below) - (Hide below)

    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 diameter and pitch combinations. For all diameters 1,6 mm to 300 mm, it offers in the form of tables the basic dimensions and tolerances for a selection of diameter and pitch combinations. It also provides the method of calculation 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 limit dimensions for fittings for fluid systems, see ISO 5855-3.
