The washer from manufacturer Cimco, type 192651, is a standard fastening component for screws with an M5 thread. It complies with standards ISO 7093, EN 27093, and DIN 9021 N, also known as fender washers. These washers serve to evenly distribute pressure between the screw and the substrate, thereby reducing stress on the contact surface and minimizing the risk of material deformation or cracking. The washer is made of steel and zinc-plated, providing a basic corrosion protection layer, particularly suitable for environments with low to moderate humidity.

Applications
The M5 washer is used in the electrical and installation industry as well as in machine building, where secure and even fastening of components is required. It is especially suitable for applications where the screw connection is made on a soft or sensitive surface, such as wood, plastic, or thin metal sheets. Using the washer prevents the screw head from sinking into the material and protects the surface from damage.

Functions and Features in Detail
The washer has an outer diameter of approximately 15 mm, which is about three times the thread diameter (M5). The inner diameter is 5.3 mm, ensuring a secure fit on the M5 screw. The zinc-plated surface offers protection against corrosion and is suitable for use in indoor environments and protected outdoor areas. The fender washer design enables stable load distribution and prevents the screw from shifting under load.

Technology Explained Simply
The washer functions as an intermediate layer between the screw and the substrate. During installation, it is placed under the screw head or nut surface. Due to the larger surface area of the washer, the screw's pressure force is distributed over a wider area. This reduces local stress and prevents indenting or damaging the surface. The zinc-plated steel surface provides a simple but effective corrosion protection, which, however, is not designed for permanent moisture or aggressive environments.

Compatibility and Accessories
The washer is specifically designed for screws with an M5 thread. It is compatible with all screws complying with standards DIN 9021 N, ISO 7093, or EN 27093. Use with other screw sizes is not intended and may result in poor fit or damage. The washers are available in a packaging unit (VE) of 100 pieces, making them suitable for series assembly or larger projects.

Installation and Mounting
Installation is done by simply placing the washer under the screw head or nut surface before tightening the screw. The washer should be clean and free of deformations to ensure optimal performance. During installation, care should be taken to avoid damaging the washer, as this could impair load distribution. The use of an appropriate screwdriver or electric screwdriver is recommended to ensure even torque distribution.

Operational Advantages
Using the M5 washer according to DIN 9021 N leads to improved fastening security and longer service life of the connection. Even load distribution reduces the risk of material fatigue and prevents the screw from shifting under load. The zinc-plated surface provides simple corrosion protection, which is sufficient for many industrial and craft applications. Standardization according to DIN 9021 N ensures worldwide uniform quality and interchangeability.

Lieske Part No.: 105420

The washer from manufacturer Cimco, type 192652, is a standard fastening component for screws with M6 thread. It complies with standards ISO 7093, EN 27093, and DIN 9021 N, also known as fender washers. These washers serve to distribute pressure under the screw head or nut contact surface, preventing material deformation and damage to sensitive surfaces. Their use is common in electrical and IT installations as well as in mechanical engineering, where even load distribution and secure fastening are required.

Washer

The washer is made of steel and zinc-plated, providing a basic corrosion protection layer. The zinc plating increases resistance to moisture and oxidation, especially in indoor or slightly damp environments. The geometric design conforms to DIN 9021 N, with an outer diameter approximately three times the thread diameter. For screw size M6, this results in an outer Ø of 18 mm and an inner Ø of 6.4 mm, matched to the screw thread.

Applications

These washers are used in the installation of electrical systems, such as securing enclosures, distribution boxes, or network components. They are also suitable for mechanical assembly of devices and machines where even load distribution under the screw head contact is required. Their use in electrical installations is particularly relevant, as they enhance the integrity of fastening screws and minimize the risk of material damage to sensitive components.

Functions and Features in Detail

The washer primarily serves load distribution. By increasing the contact surface area, the pressure force transmitted by the screw to the component is spread over a larger area. This prevents indenting or damaging the surface, especially when fastening to soft or sensitive materials such as sheet metal or plastic. The inner opening of 6.4 mm is specifically designed for screws with M6 thread to ensure a secure fit.

Technology Explained Simply

The zinc plating of the steel washer provides electrochemical corrosion protection. When in contact with moisture, a protective layer forms that shields the iron from oxidation. The flat shape of the washer, with an outer Ø of 18 mm, ensures that the load is distributed over a larger surface area. This is especially important when fastening to thin or soft materials, where local deformation could otherwise occur.

Compatibility and Accessories

The washer is specifically designed for screws with M6 thread. It is used in conjunction with M6 screws to enhance fastening security. The DIN 9021 N standard is internationally recognized and ensures interoperability with other components manufactured to these standards.

Installation and Mounting

Installation is performed by simply placing the washer under the screw head or under the nut before screwing in the screw. The washer must lie securely on the surface to fulfill its function. It is typically used in combination with a screw or nut, with the fit ensured by the precise matching of the inner Ø of 6.4 mm to the M6 thread.

Operational Advantages

Using this washer increases the service life of the fastening, as material deformation is avoided. The zinc-coated surface provides basic protection against corrosion, improving durability in damp environments. Standardization according to DIN 9021 N and ISO 7093 ensures universal applicability across various industries and applications.
