DIN 7346 Cylindrical Pin

DIN 7346 applies to cylindrical pins made of spring steel with a full-length slot.

Tubular split pins are used in mechanical engineering to tension cylindrical threaded fasteners during the assembly of units and mechanisms. The equivalent is manufactured to the international standard ISO 13337.

Pins of this type are made of carbon steel; the metal may be finished with a zinc coating applied by electroplating. Stainless steel is also used for manufacturing — products made from it feature increased corrosion resistance.
