This part of ISO 4759 specifies tolerances for flat washers of product grades A, C and F with nominal diameters of 1 mm to 150 mm inclusive, designed to be used in bolted joints in combination with bolts, screws, studs and nuts. This standard may be applied to non-flat washers however it does not include all the tolerances related to these washers. It applies to non-captive and captive washers, and to standard and non-standard washers. This document (EN ISO 4759:3:2016) has been prepared by Technical Committee ISO/TC 2 "Fasteners" in collaboration with CEN/TC 185 "Fasteners". The responsible German standardization committee is Working Committee NA 067-00-09-02 AK "Scheiben und Ringe" ("Washers and rings") at DIN Standards Committee Fasteners (FMV).
