ISO 3912 is a semi-circular segmental key. A key is a type of fastener that provides a rotational connection to a structure. Unlike prismatic dowels, segmental dowels are notoriously simpler. They are also particularly precise and can be interchanged without the need for manual setting and fitting. Segmental keys are characterized by their strong fixation in the shaft groove. This is what prevents it from distorting, deforming or turning out.
Materials used to manufacture ISO 3912 keys
ISO 3912 keys are made exclusively of steel.
Areas of application for ISO 3912 keys
ISO 3912 segmental key is used in assemblies in mechanical engineering and other industrial production. They can often be found in various electrical tools and mechanisms. ISO 3912 is indispensable because the assemblies connected with their help are more durable. These keys are deeper in the splines, which strengthens the connection of the parts. Preparation of grooves in shafts for this type of fastener is quite simple, so it is not costly.
ISO 3912 is widely used in mechanical engineering, as a part of cars and mechanisms, but can also be seen in construction.
