DIN 125A2 is a standard established by the Deutsches Institut für Normung e.V. (German Institute for Standardization) that outlines the specifications for flat washers. These washers are typically used in conjunction with bolts and nuts to distribute loads, reduce the likelihood of deformation, and prevent damage to the surface material upon which they are fastened. The A in the designation signifies that the washers are of type A, which typically refers to an extensive range of sizes, providing flexibility in fastening applications.
