ISO 7093-1 - Plain washers, large series, product grade A

Automatically build standard products in SOLIDWORKS with TSFP.

Plain washers, large series, product grade A, with an outside diameter about three times the thread size, against about twice in the normal series ISO 7089. Current replacement for DIN 9021, but the sizes are not identical: it drops sizes 2.5 and 7, adds 22, 27 and 33 and has narrower holes from size 18. Includes both the preferred sizes and the non-preferred sizes 3.5, 14, 18, 22, 27 and 33. The grade C version is ISO 7093-2.
