German Metric Thread ID Template
Ideal for counter and field identification of German Metric DIN threads
GBS Collateral Item #70086290575800
Instructions
Female Threads
1.
Use the 12° or 30° angle, as shown in the
image to the right, to verify that the seat is
12
° or 30° (see note)
2.
Use the step gauge to determine Inside
Diameter of female port
3.
Measure Tube OD with the Tube Inside
Diameter Gauge
4.
Use Thread ID Table: DIN 2353 along with
measured Tube OD to determine if tube is
“
Heavy” or “Light” Series
Male Threads
1.
Use the 12° or 30° angle, as shown in the
image to the right, to verify that the seat is
12
° or 30° (see note)
2.
Use Fitting Inside Diameter Gauge to
measure Inside Threads
3.
Refer to Thread ID Table: DIN 3863 along
with measured Thread OD to determine
Metric Male Thread. Rule of Thumb: on Male
Thread, measure the ID of the machined
surface and subtract 1mm to achieve
tube OD. For example, when measuring
a heavy-duty series Male on a M14 x 1
f
thread, the caliper will measure 7mm (7mm-
1
mm=6mm)
Note: If measured angle is not 12° or 30°, use the
Fitting Identification Section in our Hydraulic Hose
Catalog Appendix to identify.
Inclusive Angle is the entire angle contained in
the machined surface. Each side of the surface
measures 1/2 of the total angle (e.g. 24° x .5 = 12°).
