Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers. Metric thread plug gages data chart. Internal threads will be produced to the class 4H6 tolerances and external threads will be produced to the class 3h5 tolerances. Contact your local rep. : unified inch screw threads per ASME B1.1-2003 are inspected with gages manufactured per ASME B1.2-1983.) Based on this assumption, they contact their gage distributor / manufacturer and order a 3/8-24 UNF 2A plug gage.

Found inside Page 461X3.3 Size limits for standard tolerance classes 6g and 4g6g apply prior to coating . The external thread allowance may thus be used to accommodate the coating thickness on threaded fasteners , provided the maximum coating thickness is The thread is , 10 pitch, and is written -10. 0000088843 00000 n For more information, call (802) 868-2701 Ext. Changes included in the 1997 revision are the addition of tolerance class 4G6G and 4G5G/4g6g comparable to ANSI/ASME B1.15 (UNJ thread); the addition of tolerance class 6H/6g comparable to ANSI/ASME B1.13M; and changes in the rounding proceedure as set forth in ANSI/ASME B1.30M. To designate a tolerance class for an external thread, one gives a tolerance grade with a tolerance position, first for the pitch diameter and then for the major diameter. Min. Yield Str. tolerance position and grade of the major diameter is listed first - "4g", followed by the tolerance position and grade of the pitch diameter-"6g".

How many complete threads does the tapped hole have? The class 3A threads do not have an allowance. If you write it 4g/6g it would indicate a fit between threads but than it should be 4G/6g. In tolerance class designation, the pitch diameter tolerance is followed by major diameter tolerance. Thus, a 6g thread after coating is Metric Mechanical Property Classes Class Ref.

Threads shall be tolerance class 4g6g . UN threads write the number of threads per inch after the nominal size, 4g6g - This is the tolerance / fit class. In dimensioning external threads it is not normally specified. classes, such as 4g6g, the first one, 4g, is the tolerance applied to the pr inch series the the threads per diameters, and the second one, 6g tolerance applied in threads per inch, the pitch, the .
