DIN 125 Flat Washer (Type A) is a flat, circular metal disc used under bolts or nuts. Its primary purpose is to distribute the clamping force over a larger surface area, ensuring a secure and stable connection. This type of washer is typically made from steel, stainless steel, or brass and may have a coating for corrosion resistance. DIN 125 washers are commonly used in general mechanical assembly applications and help protect the surfaces joined by bolts or nuts. They serve as a standard and durable fastening element.
