Washers in accordance with standards – DIN washers for mechanical engineering and industry

High-quality washers for secure connections

Washers, especially standard washers and DIN washers, are essential connecting elements in mechanical engineering and industry. They ensure even load distribution, protect surfaces, and increase the safety of screw connections. Our range includes a wide selection of DIN washers that are characterized by high quality and reliability.

DIN washers according to standards – quality that connects

Our standard washers are manufactured according to the specifications of the German Institute for Standardization (DIN) and meet the highest industrial standards. Whether classic washers, spring washers, or special lock washers – you will find the right washers for your application with us. DIN standards facilitate selection and ensure compatibility with other fasteners such as DIN screws.

Flat washers according to DIN – explained in a nutshell

Flat washer ISO 7089 / DIN 125

Flat washers according to ISO 7089 (formerly DIN 125 A) are form A washers without a chamfer. They distribute the load evenly and protect the surface in screw connections. The ISO standard replaces DIN 125 and provides internationally uniform dimensions and tolerances.

Available in steel, stainless steel, brass, or plastic, they are suitable for a wide range of applications in mechanical engineering, trade, and industry. Typical sizes range from M3 to M36 – depending on the area of application, they are also available in a hardened version for high loads.

Flat washer ISO 7091 / DIN 126

Washers according to ISO 7091 (formerly DIN 126) are form A washers with a reduced outer diameter. They are particularly suitable for space-saving screw connections and protect the surface from pressure marks. The ISO standard replaces DIN 126 and ensures internationally uniform dimensions.

Available in steel, stainless steel, or brass, these washers are ideal for applications in precision engineering, mechanical engineering, and electrical engineering. Sizes range from M2 to M36—also available in hardened versions for demanding connections.

Hexagon head screws at a glance: Robustness and versatility for your applications

Hexagon screw with flange DIN 6921

Hexagon screws to DIN 6921 have a hexagonal head and an integrated flange. This flange distributes the load over a larger area, which protects the material and makes the connection more stable. Some variants of these hexagon head bolts have locking teeth under the flange that prevent the bolt from loosening.

Hexagon fitting screw with long threaded pin DIN 609

Hexagon fitting screws in accordance with DIN 609 are screws with a hexagonal head and a long threaded tang. The threadless shank of these screws provides a particularly accurate fit, which is essential for precise applications. The threadless shank completely fills the hole, which prevents wobbling or instability.

Standard washers of product class A – ISO 7092 vs. ISO 7093-1

Flat washer ISO 7092/DIN 433 – small series

ISO 7092 washers (formerly DIN 433) are part of the small series and are designed for screws with small head diameters. They evenly distribute the load and protect the surface. Product class A stands for high dimensional accuracy and narrow tolerances.

Available in steel, stainless steel, brass or plastic – with degrees of hardness ranging from 100 HV to 300 HV. Typical sizes: M2 to M36. Ideal for compact connections in mechanical engineering and precision engineering.

Flat washer ISO 7093-1/DIN 9021 – large series

Flat washers according to ISO 7093-1 (formerly DIN 9021) belong to the large series and are distinguished by a particularly large outside diameter. They distribute the load in screw connections over a wide range and protect sensitive surfaces. Product class A stands for high dimensional accuracy and narrow tolerances.

These washers are ideal for applications in wood and steel construction, as well as for use in humid rooms and outdoors. They are available in materials such as steel, A2 stainless steel/A4 or brass with degrees of hardness ranging from 200 HV to 300 HV. Typical sizes range from M3 to M24.

Advantages of washers

Washers, also known as washers, are essential fasteners that ensure stability and safety in numerous applications. They offer several advantages at once:

Load distribution

Flat washers enlarge the contact surface under screws or nuts, thus preventing them from sinking into the material. This evenly distributes the load and makes the connection more stable.

Surface protection

The use of washers protects sensitive surfaces from damage such as scratches or pressure marks-ideal for high-quality materials.

Secure grip

Washers reduce the risk of loosening screw connections by damping vibrations and stabilizing the prestressing force. Spring lock washers are particularly suitable to prevent automatic loosening.

Versatile applications

Be it in mechanical engineering, the automotive industry or the trades: washers are available in different sizes, materials and in accordance with DIN standards. They are suitable for numerous applications, from simple assembly work to complex constructions.

Corrosion resistance

Many discs are made of stainless steel or are provided with special coatings that protect them from corrosion and extend their service life.
