36、ashers.It does not apply to dynamic disc springs.Washers of product grades F and A are intended to be used with bolts, screws, studs and nuts of product grades A and B; washers of product grade C are intended to be used with bolts, screws, studs and nuts of product grade C.NOTE The product grade ref
37、ers to a specific tolerance range related to dimensional and geometrical characteristics (product grade F for fine tolerances, product grade A for precise tolerances, product grade C for large tolerances).Annex A presents tolerances taken from ISO 286-1 and ISO 286-2.2 Normative referencesThe follow
