Explanation of Columns (Section IV). a. NATIONAL STOCK NUMBER (NSN) INDEX. (1) STOCK     NUMBER     column. This column   lists   the   NSN   by   National   Item   Identification Number (NIIN) sequence.  The NIIN consists of the last nine digits of the NSN (i.e., 5305-01-o74-1467 ).  When NIIN using this  column  to  locate  an  item,  ignore the  first  4  digits  of  the  NSN.    However,  the  complete NSN   should   be   used   when   ordering   items   by   stock number. (2) FIG.    column.    This  column  lists  the number of the figure where the item is identified/located. The   figures   are   in   numerical   order   in   Section   II   and Section III. (3) ITEM    column.        The    item    number identifies the item associated with the figure listed in the adjacent FIG.  column.  This item is also identified by the NSN listed on the same line. b. PART  NUMBER  INDEX.    Part  numbers  in this    index    are    listed    by    part    number    in    ascending alphanumeric   sequence   (i.e.,   vertical   arrangement   of letter   and   number   combination   which   places   the   first letter or digit of each group in order A through Z, followed by the numbers 0 through 9 and each following letter or digit in like order). (1) CAGEC    column.        The    Commercial and   Government   Entity   (CAGE)   Code   (C)   is   a   5-digil alphanumeric   code   used   to   identify   the   manufacturer, distributor, or Government agency, etc., that supplies the item. (2) PART   NUMBER   column.      Indicates the primary number used by the manufacturer (individual,   firm,   corporation,   or   Government   activity), which controls the design and characteristics of the item by means   of its engineering    drawings,    specifications    standards,    and inspection  requirements  to  identify  an  item  or  range  of items. (3) STOCK     NUMBER     column. This column lists the NSN for the associated part number and manufacturer    identified    in    the    PART    NUMBER    and CAGEC columns to the left. (4) FIG.    column.    This  column  lists  the number of the figure where the item is identified/located in Sections II and III. (5) ITEM   column.      The   item   number   is that  number  assigned  to  the  item  as  it  appears  in  the figure referenced in the adjacent figure number column. c. FIGURE AND ITEM NUMBER INDEX. (1) FIG.    column.    This  column  lists  the number of the figure where the item is identified/located in Sections II and III. (2) ITEM   column.      The   item   number   is that  number  assigned  to  the  item  as  it  appears  in  the figure referenced in the adjacent figure number column. (3) STOCK     NUMBER     column. This column lists the NSN for the item. (4) CAGEC    column.        The    Commercial and  Government  Entity  (CAGE)  Code   (C)   is   a   5-digit alphanumeric   code   used   to   identify   the   manufacturer, distributor, or Government agency, etc., that supplies the item.
