Whitworth Fine Thread 1 DIN 239

The Whitworth Fine Thread 1 DIN 239 is a British fine thread belonging to the Whitworth thread family. It is a historical thread that is no longer in use today. The Whitworth Fine Thread 1 DIN 239 should not be confused with the current Whitworth Fine Thread according to BS 84.

The Whitworth Fine Thread 1 DIN 239 has a flank angle of 55°. The external diameter is given in mm, and the pitch in threads per inch. The pitch for the Whitworth Fine Thread 1 DIN 239 is consistently 4.

In the thread designation of the Whitworth Fine Thread 1 DIN 239, reference is made not to the external diameter, as is usually the case, but to the core hole diameter. Also included is the pitch of 4 in the form of 1/4″, so the full designation might be, for example, W 72 x 1/4″. The short designation for the Whitworth Fine Thread 1 DIN 239 is W-4 Gg.

The Whitworth Fine Thread 1 DIN 239 is no longer common. However, if you need dies or taps for this thread type, we will of course be happy to manufacture a custom order for you.
