Product description


Domed gear knobs GN 719.2 are very often used in place of ball knobs DIN 319 for use on gear levers and shafts. Operating knobs are very often chosen for ergonomical reasons.

Domed gear knobs GN 719.2 with bore (B) are mounted by driving them over the shaft with a plastic hammer. A threaded shaft is not required. The shaft end should preferably be slightly rounded or phased (30°).
