Reinforced washer DIN 7349

  DIN 7349 is another German standard that defines the parameters and dimensions of a reinforced washer used to distribute loads and ensure secure fixation of screws and nuts in structures subject to high loads. DIN 7349 A reinforced washer is made of carbon steel or stainless steel and has an increased outer ring diameter and inner hole diameter, which provides a wider contact area between the washer and the surface on which it is placed. This allows for even load distribution and prevents damage to the surface due to concentrated loads.

Fastening group DIN 7349

      DIN 7349 washers belong to the stainless steel fastener group.

Materials for the manufacture of DIN 7349 washers

      DIN 7349 washers are made of the following materials: 

• Steel, which can optionally be coated with zinc, yellow zinc and hot zinc. Zinc protects against corrosion if the fastener is to be used in aggressive environments.
• Stainless steel. Steel grade A2 allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.

Areas of application for DIN 7349 bolts

     DIN 7349 Reinforced washer is used in structures subjected to high loads and where it is necessary to ensure reliable fixation of connecting elements such as screws and bolts. The scope of their application is very wide and includes the following industries:

• Mechanical engineering: reinforced washers are used to connect various parts of machinery and equipment subject to high loads.
• Automotive and aviation industry: reinforced washers are used in the automotive and aviation industry to connect various components of vehicles subjected to high loads.
• Shipbuilding: reinforced washers are used to connect various components of ships and other marine equipment subjected to high loads.
• Construction: Reinforced washers are used in the construction industry to connect various structures and building elements that are subject to high loads.

     All of these industries require the use of high-quality connecting elements, such as reinforced washers DIN 7349, to ensure reliable and safe operation of structures.
