ISO 3161:1999 Aerospace – UNJ threads – General requirements and limit dimensions
CDN $353.00
Description
This International Standard specifies the general requirements and limit dimensions of inch series UNJ threads with
controlled root radius for aerospace construction.
It determines the basic triangular profile for this type of thread and gives a system for designating the diameter and
number of threads per inch combinations. For all diameters 0,060 in (1,524 mm) to 6,000 in (152,4 mm), it offers in
the form of tables the basic dimensions and tolerances for a selection of diameter and number of threads per inch
combinations. It also provides the method of calculation for the dimensions and tolerances for any diameter and
number of threads per inch combination not given in the tables, including threads with a diameter in excess of
6,000 in.
