I stripped the cable set screw on my Dyad and couldn't find the screw dimensions anywhere online. I was able to source a replacement and thought I would post so that those searching can find the info.

The cable set screw is an M3 x 4 mm length.

I picked one up from a speciality fasteners store (Pacific Fasteners in Vancouver).

In a pinch, any M3 bolt should work. Having a head sticking out doesn't affect function, though the 4 mm set screw is much sleeker.

When tightening the set screw, use an unworn 1.5 mm allen key. I'm pretty sure mine stripped because my allen key was sloppy.
