DIN 433 Small O.D. Flat Washer

FULLERKREG supplies DIN 433 small outer diameter flat washers across a full range of materials and surface treatments. DIN 433 (ISO 7092) washers feature a reduced outer diameter compared to standard DIN 125 washers, making them the correct choice for use with pan head screws (DIN 7985) and cheese head screws (DIN 84) where the washer must seat within the head recess. All products are manufactured to strict DIN / ISO dimensional tolerances and are available for wholesale and bulk supply.
