DIN 7978 Non-hardened cone pin is a hardware product that belongs to the category of locking pins and is used, as a rule, in the industrial sector (automotive, instrumentation, mechanical engineering) and medicine. They consist of a cone-shaped rod and an internal thread.
For the effective installation of a DIN 7978 pin, it is necessary to securely fasten the elements so that their holes, corresponding to the pin diameter, perfectly match the longitudinal axis. Using a special tool, the pin is inserted firmly into the prepared hole. As a result, the friction force between the surface of the metal product and the walls of the holes increases so much that it prevents not only the fastener from falling out, but also easy self-release.
Materials for the manufacture of DIN 7978 pins
DIN 7978 pins are also made of steel.
Areas of application for DIN 7978 pins
If we compare tapered and cylindrical pins, the former are more versatile and effective. It is the conical shape that makes it possible to reuse the fastener. At the same time, the accuracy of the fastened planes, parts, and assemblies remains unchanged.
DIN 7978 pins are widely used in mechanical engineering and instrumentation.
