Order example:
Ball knob DIN 319 – M 20 x 5
Ball knob DIN 319 – M 40 x 12
- Form M DIN 319 ball knobs are used where the opposing part does not have a thread. They are lightly tapped onto the mating part (shaft tolerance h9, shaft end lightly chamfered) using a soft faced hammer and hold with adhesive.
- As the material thermoset is very brittle, where possible the thermoplastic versions (only Form M size 16 to 40 mm) should be preferred.
- Other versions and colours on request.
Plastic:
- Thermoset, PF 31, highly polished, black
