1.4 Acceptability
Acceptability of product threads shall be in accordance with ASME B1.3. Gages and gaging are in accordance with ASME B1.16M.
1.5 Reference Temperature
The reference temperature is 20CC for dimensions defined by this system.
1.6 GeneraL Symbols
The general symbols used to describe the metric screw thread forms are shown in Table 1.
1.7 Units
All dimensions and all values in the formulas are expressed in millimeters unless otherwise noted. Values in terms of sharp vee-th read height (height of fundaniental triangle), H, are used to be consistent with ISO Standards, but actual formulations and calculations are based on values of pitch, P. See Table 2.
1.8 Federal Government Use
When this Standard is approved by the Department of Defense and Federal Agencies and is incorporated into FED-STD-H28/21, Scru’ Thread StandarLc for Federal Services Section 21, the use of this Standard by the Federal Government is subject to all the requirements and Ii mitations of FED-STD-H28/21.
2 TERMINOLOGY
2.1 Definitions
allowance: the prescribed difference between the design (maximum material) size and the basic size. It is numerically equal to the absolute value of the ISO term fundan ental deviation.
NOTE: Ath’wuice i not em ISO mvtric crvw thread tenn hut will be wied together with the ISO term findarncntal deviation.
basic thread profile: the cyclic outline, in an axial plane, of the permanently established boundary between the provinces of the external and internal threads. All deviations are with respect to this boundary See Figs. 1 and 4.
bolt thread (external thread): the term used in ISO metric thread standards to describe all external threads. All symbols associated with external threads are designated with lowercase letters. This Standard will refer only to external threads in accordance with U.S. practice.
