Countersunk head rivet DIN 661 4x20 copper

Product detailed description

The copper rivet with a countersunk head, dimensioned according to the DIN 661 standard, with dimensions 4x20 mm, is intended for use in applications where high conductivity and corrosion resistance are required. This rivet is made of copper, which guarantees its excellent electrical and thermal properties, and is suitable for joints where reliable and permanent fixation is required.

The DIN 661 standard defines the dimensions and tolerances for countersunk rivet heads, which ensures compatibility and standardization within various industrial applications. The dimension 4x20 mm indicates a shank diameter of 4 mm and a length of 20 mm, which is suitable for thin-walled materials where it is important to minimize protruding parts of the joint.

The countersunk head is designed to be flush with the surface of the material after application, thus achieving an aesthetic and functional joint without protruding parts. This type of head is ideal for applications where a smooth surface is required, such as in electronics or in structures with aerodynamic requirements.

Copper rivets are often used in the electrical industry, where their conductive properties contribute to the efficient transmission of electrical current. In addition, the copper material provides excellent corrosion resistance, which extends the life of the joint even in harsh conditions.

This rivet is also in accordance with the ČSN 022311 and ISO 1051 standards, which guarantees its applicability in international projects and applications where specific technical requirements must be met. It is suitable for professional use in industrial sectors where the emphasis is on the quality and reliability of fasteners.
