About the 1755560 Flat Washer M2.5, A4 Stainless BN
Bossard part number 1755560 is a flat washer to DIN 125, supplied under the Bossard BN 671 catalogue series, in the M2.5 nominal size. DIN 125 is the long-established European standard for plain flat washers used under screw heads and nuts: the washer spreads the clamping load of the fastener over a larger bearing area, protects the mating surface from damage during tightening, and bridges clearance holes. This washer is manufactured from A4 austenitic stainless steel, the acid-resistant grade, which makes it the correct pairing for A4 screws and nuts so that the whole joint shares the same corrosion behaviour. Miniature washers in this size range are standard hardware in electronics, instrument and small-mechanism assembly. Exact outer diameter and thickness follow the DIN 125 dimension table for the M2.5 size and can be confirmed with the manufacturer’s data sheet at quotation stage.
