Binder 691 thread pitch

[MagnetoSound]

Does anyone happen to know the thread pitch in the 691 connector?

I’m playing around with some 1” metal tubes with a view to fabricating a mic similar to the KM25x or C28 type. It would be really nice to thread the outside of the tube to make it Binder-compatible so that I can screw a 691 connector directly onto the end, but I cant seem to find any info on the thread size other than M25.

Standard metric ’fine pitch’ sizes seem to range from 1.0mm to 1.25mm to 1.5mm …

Can anyone help?

According to my thread gauge it is M25x1mm.

Thanks! That’s a bloody useful thing to have.

Yep, it was inside a thread cutter set box from my grandfather which I had for some years. But I only found out what it was some short time ago. Use it now pretty often.

They’re like £5 on eBay. Who knew?
