This International Standard gives details for the manufacture and use of gauges for checking ISO general-purpose metric screw threads with a basic profile in accordance with ISO 68. Thus, wear life of the coated gauge is significantly higher… between 5 and 7 times the life of a conventional gauge (more), Gauges for testing pipe threads where pressure tight joints are made on the threads to BS 21: 1985 and ISO 7/2 2008 (more), Gauges for testing the taper threads specified in BS 341: Part 1: 1991 (more), Gauges for testing threads to American National Standard ANSI/ASME B.1.20.1 - 1983 (more), NPTF Thread Gauges for testing threads to American National Standard ASME B1.20.5 - 1991 (more), Plain gauges generally fall into two types:- plugs for internal holes and rings or gaps, sometimes referred to as ‘snap’ or caliper gauges for shafts. 2. Thread Ring gages are available in ACME , Straight Pipe and Taperpipe styles.. Note: This screw chart is not comprehensive of all available standard threads as provided by the standard. GD&T Training Geometric Dimensioning Tolerancing ; SCREW THREAD GAUGES • When a large of component with screw thread are to be produced then measurement of various element of screw thread will be very expensive and time consuming gauges are scale less inspection tools at rigid design, which are used to check the dimension of manufacturing parts. [citation needed]The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres (e.g. ANSI/ ASME EXTERNAL Screw Thread Size Chart. Pass/Fail assessment of a NOT GO gauge for the ISO class gauge system has been set as not to be screwed in more than two revolutions. Ring Thread Gages and Setting Plugs NOMINAL SIZE X TOL.
