Pg Steel Conduit Threads per DIN 40430 STEEL CONDUIT THREAD; DIMENSIONS
Pg Steel Conduit Threads are manufactured in accordance with DIN
40430 STEEL CONDUIT THREAD; DIMENSIONS. The Pg thread series is
designed specifically for steel conduit because of the thin wall
cross section of the steel conduit. The thin wall thickness requires
a shorter profile thread that will not break through the outside
diameter of the steel conduit during the machining process. The
80° included angle of the Pg thread form gives a shorter profile
than the more common 60° included angle found in the Unified
National thread series and the Metric thread series. There is some
discussion about replacing the Pg Steel Conduit Thread per DIN 40430
with a 60° version as specified in BS EN 50262 CABLE GLANDS
FOR ELECTRICAL INSTALLATIONS and/or DIN EN 50262 METRIC CABLE GLANDS
FOR ELECTRICAL INSTALLATIONS.
Standard Pg Steel Conduit Thread Sizes per DIN 40430 STEEL CONDUIT
THREAD; DIMENSIONS
Pg7: Nominal Major Diameter = 12.5mm; Threads-Per-Inch = 20
Pg9: Nominal Major Diameter = 15.2mm; Threads-Per-Inch = 18

Pg Steel Conduit Thread Plug Gages per DIN 40430 STEEL CONDUIT
THREAD; DIMENSIONS
The standard: DIN 40430 STEEL CONDUIT THREAD; DIMENSIONS specifies
the requirements for the thread plug gages. A unique aspect of the
Pg Steel Conduit Thread Plug Gage is that the NOGO member is a plain
cylindrical gage. This actually works because as the thread is machined
the crest of the thread form comes to a point. As the thread size
is changed, the position of the point changes and thus can be measured.
The GO member works in the normal manner by checking the maximum
material condition.
