The Southern adjustable thread ring gage features the Automatic Helix Adjustment.  The gage starts round and stays round through all adjustments.  Thread flanks stay in alignment through the entire adjustment of the gage.  Simple and sure adjustments will stand up under severe shop use.  Aluminum gage bodies anodized green for GO and red for NO GO provide quick positive identification.  All thread inserts are made of an oil hardening tool steel.  Class and tolerances conform to ANSI B1.2 & ANSI B1.16M Gage Standard and/or H28 Handbook.
