ISO 2903:2016根据ISO 2902规定了公制梯形螺纹的公差系统。公差指符合ISO 2901的设计轮廓。
公差系统不适用于对轴向位移有特殊要求的梯形螺纹,例如机床导程和进给螺钉及螺母。
ISO 2903:2016 specifies a tolerance system for metric trapezoidal screw threads in accordance with ISO 2902. The tolerances refer to the design profile in accordance with ISO 2901.
The tolerance system does not apply to trapezoidal screw threads with special requirements on axial displacement, for example, machine tool lead and feed screws and nuts.
