When ball knobs DIN 319 (Press on type) type L and M are used the shaft does not require a thread.
During mounting, easy blows with a soft hammer are sufficient to drive the knob into place, the shaft end should be slightly rounded or chamfered (30°).
Before the assembly of the knobs, type L the tolerance ring is to be inserted into the drilling. Further it is to be noted that the button is put on perpendicular and / or axially parallel. Otherwise the knob may break.
Ball knobs, type M are a more economic solution.
Ball knobs DIN 319 in sizes 30 and 35, as well as various thread of type C and ball knobs made of technopolymer (KT) are not on the official DIN standard sheet.
Ball knobs DIN 319 made of steel, aluminum and stainless steel are not on the official DIN standard sheet.
