Metric fender (large OD) washers in 316 (A4) stainless steel to DIN 9021 / ISO 7093, sized by bolt diameter. An outside diameter about three times the bolt size spreads the load on thin sheet and soft materials. 316 stainless adds molybdenum for salt water, chlorides and chemical exposure — the choice for marine and coastal work. 8 sizes (M3 to M20). Plain finish. Sold in production-volume bulk packs.
