Fastening elements	Stamped parts
Fasteners are used in various geometries and dimensions to establish screwed connections. Depending on the area of use, they are required to meet high requirements. For example, bolts on a truck exhaust are subjected to high temperatures of between 350–500 °C and therefore need to be especially temperature resistant. As a rule, fasteners in the engine compartment need good fastening properties (coefficients of friction) - particularly where different materials are fastened together.	The engine compartment of a truck contains numerous stamped parts, clips and springs made from steel and stainless steel. These components need to display good protection against contact corrosion whilst at the same time offering good sliding properties.

Solutions currently commonly used for concrete screws

Depending on component, DÖRKEN offers various solutions for optimal corrosion protection in the engine compartment: from the use of pure zinc flake systems to the combination of different base coats with an organic or inorganic topcoat. Our specially-developed systems enable a high degree of corrosion protection to be achieved with comparatively very thin coats. In the case of fasteners, secure fastening is therefore achieved against different backings, whilst also effectively avoiding contact corrosion. One particular advantage of the zinc flake system is that it can also be used in components with complex structures and cavities.

Chassis

The truck chassis plays a key role here: it consists of numerous components that form a complex whole that is responsible for aspects such as driving dynamism and safety. Technically sophisticated and safety-relevant systems are therefore essential.

Interior

Components in the interior of vehicles are not exposed to corrosive stresses to such an extent. It is important in this area to ensure the functionality of parts that in use on a daily basis.

Trailer

Whether it is flatbed vehicles, box trucks or tipper trucks: a wide range of components are used in and on truck trailers. With the long-term use on roads and highways, the components are subjected to a range of different stresses, such as stone impact, dirt, frost and continuous cleaning cycles. The long-term ensuring of component functionality and operational readiness of the trailer is therefore essential.
