AbolishedTrapezoidal screw threads-Part 4:Tolerances
梯形螺纹 第4部分：公差
Application Summary AI generated
This standard specifies the tolerance system for trapezoidal screw threads, defining acceptable deviations for pitch, flank angle, and major/minor diameters. It is applied in mechanical engineering for manufacturing lead screws, machine tool feed mechanisms, and lifting devices where precise thread fit and load distribution are critical. The standard ensures interchangeability and consistent performance in applications like lathes, presses, and jacks.
