Remote release screw thread

[BJC0000]

Can anyone offer any details about the screw thread used to connect remote release cables to shutters?
I can't find any info on this site.
I know they are unusual in that the threads are tapered. How are they formed?
Is it possible to buy a drill bit / tap / die set to create your own?
ANY information gratefully received.

-) there are two of such, the american with straight thread, the european with conical thread; you likely refer to the european one

-) it is a thread standardized by german DIN standard

-) it is cut by a tapered tool, similarly as is done with any straigh thread too

-) a tap is in the 200€ range, thus exchanging a button is the way to go in most cases

If you are researching this, you may find that "remote release" refers more often to electrical or optical versions, while "cable release" is more commonly used for most mechanical versions.
There are also versions that use air pressure.
All three can be set up to use the same threaded connection.

The pneumatic releases use a cylinder with piston that is screwed into the cable release socket. Basically a good approach.
The electrical releases are using an electromagnet screwed into the cable release. These magnets are likely to induce a shake onto the camera. Test such device on such shake before.

If you are curious as to the specs on the European taper thread cable release, here is the ASA Standard from many years ago:

There was a fairly complete discussion on this topic on this forum at least once before .
Use the search function and you'll find it as it will answer all your questions you've asked , and the ones you haven't !
As noted , it's a cable release your looking for , not a remote release .

IIRC , the just if it was , for a tapered tap you need a special tap that are very hard to track down .

Well, I define "remote release" as superior term subsumising cable, pneumatic, radio, infrared and sound release.
The first 3 could be coupled to this thread, by commercial devices.

Maybe the term though is more common for proprietary releases at modern cameras.

Before American camera makers adapted the tapered thread for mechanical shutter release cables, their cables had a no. 5-44 thread.
