Outside diameter information
The current catalogue data contain a discrepancy: the M4×20×1,25 variant heading indicates 20 mm, while the table gives d2 = 12 mm. The outside diameter remains to be confirmed; neither value has been accepted as a confirmed product dimension. The catalogue data do not specify a DIN or ISO standard, so the standard also remains to be confirmed. No additional tolerances or hardness are specified.

Scope of delivery and weight
Sales unit: one full pack of 100 washers. Catalogue weight of the quantity sold: 0,254 kg, calculated from the catalogue weight of 2,54 g/pc. × 100 pieces. This is the catalogue weight of the quantity, neither an in-house measurement nor a confirmed gross box weight. The weight comes from the individual card and was not calculated from the unconfirmed outside diameter. The images and box illustrate the product family. The diagram shows labels d1, d2 and s; its proportions do not confirm d2 and are not manufacturing documentation.
