| PG screw thread
The PG screw thread, also known as Panzergewinde, is a technical standard that originated in Germany. It was established and codified by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. The specific standard for the PG screw thread is DIN 40430.
PG screw thread sizes are designated with the prefix “PG” followed by a nominal number. This number roughly corresponds to the maximum cable diameter, in millimeters, that can pass through the conduit. Due to the relatively thin walls of the conduit, the thread depth is limited. As a result, a thread angle of 80° is utilized in the PG screw thread standard.
