threaded knob / star / polyamide
PlacoGrip® Quick clamping star knobs
Quick clamping star knobs are for those applications where the grip, after slackening, is completely removed and must then be rapidly replaced in the clamp position.
The knob is placed diagonally on the threaded bolt and is then brought into a right-angled position so that it clicks into the thread of the bolt.
A short turn is enough to clamp it.
The use of these knobs is recommended only for situations where high clamping forces do not have to be applied
