Provides the selection of tolerances used in the preparation of ISO product standards for washers for bolts, screws and nuts with thread diameters from 1 up to and including 150 mm and product grades A and C, which refer to the quality of the product and to the size of the tolerances where grade A is the most precise and grade C is the least precise. Recommends that these tolerances should also be used for non-standardized washers.
