![]() ISO 2768 provides general standard metric tolerances (mm) for linear and angular dimensions without individual tolerance indications in four tolerance classes. A circularity tolerance would tell you if the non-perfect circular bar shapes are acceptable. The Lesson: an engineering drawing tolerance would tell you if the measured values above are within the acceptable range for the diameter dimension. The bars also vary in length and upon closer inspection, they’re not perfectly circular.Ĭan you still use them? If not, can you reject them and demand that the vendor redo them at no cost? How close to the Ø50mm should you really be?
