Flat washer reinforced DIN 1440

     DIN 1440 A flat washer (finger washer) is a fastener used primarily on steel pins or pins. Such pins are often used to attach attachments or trailed equipment. Such washers are an important auxiliary element in the creation of quick-release connections that operate under heavy loads.

DIN 1440 fastening group

     DIN 1440 flat washers are most often made of stainless steel and belong to the stainless fastener group.

Materials for the manufacture of DIN 1440 washers

     DIN 1440 washers are made of the following materials:

• Steel, which can optionally be coated with zinc. Plated zinc protects against corrosion if the fastener is to be used in aggressive environments.
• Stainless steel grades A2 and A4. Allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.

Application range of DIN 1440 washers

     The thumb washer is installed in places of constant dynamic and vibration loads to prevent loosening and loosening of the connection. Due to its shape, the reinforced washer ensures a stronger contact between the fastener and the product.

     DIN 1440 is used in mechanical engineering, construction and the automotive industry.
