About the Flat Washer, Large, M8x1.5, A2 Stainless Steel
This is a large-series flat washer to Bossard standard BN 84542 — flat washers without chamfer, series L (large) — in the M8 size. Distributor data for the M8 part lists a 22 mm outside diameter and 1.5 mm thickness, consistent with the M8x1.5 figures in the item name, with the oversized outer diameter giving a much wider bearing footprint than a normal-series washer. The material is A2 austenitic stainless steel at a hardness of 150 HV, and Bossard references the dimensional basis NF E 25-514 L for the series. Large-series washers are chosen to bridge slotted or oversized holes and to reduce bearing pressure on soft or thin materials. As a Flat Washer Large M8x1.5 A2 Stainless part it pairs naturally with A2 M8 bolts and nuts so the whole joint shares one corrosion class.
