Metric trapezoidal screw threads-Basic dimensions
UDC 621.882.082.4
GB 5796.3--86
Replaces GB 781-65
This standard specifies the basic dimensions of trapezoidal threads according to GB5796.1--86 "Trapezoidal thread profile" and GB5796.2-86 "Trapezoidal thread, diameter and pitch series". This standard is equivalent to the international standard ISO2904-1977 "ISO metric trapezoidal thread-basic dimensions". The names, codes and relationship of the basic dimensions of the thread are listed in Table 1. Table 1
