sorby RS200 kt -screw thread

[Shay Vings]

Anyone know what thread the cap screws are which hold the cutters?

The supplied allen key is slipping or I may have burred over the screw threads through overtightening but my 3mm a/f allen key is too sloppy and a 1/8 key fits better.

Yet the thread major dia is 4.82mm suggesting it might be M5 but then my M5 screws don't fit the hole either!

My Sorby tools appear to use 2BA with 1/8" allen key.
Although the thread diameter is full at 0.1875" on my samples, (0.185" being more typical) 32 TPI (Pitch .81mm)

Very close to 5mm coarse. (0.196") .8mm Pitch.

I finally remembered to look at what I use - the packet has 'M5 x 16 Socket Csk Screw A2' on it. Bought from Screwfix. I think I also have some with a larger socket head on them which takes a larger allen key and makes it easier to tighten/untighten.
