The dimensions of these collets are similar to those used by many European manufacturers including Schaublin, Bergeon & Wolf Jahn except that the drawbar thread is a coarser pitch. The standard thread pitches for 8mm Horological collets are 0.635 mm (40 tpi) and 0.625 mm. Drawbars manufacture is made easy as taps for M7 x 0.75 are readily available - they can also be purchased ready made.
