Precautions for Use

The height of hex head screws and hex nuts should not exceed L1 max.
It may not be possible to attach a cap.

Assembing method

  1. Fit the hex bolt or hex nut securely into the knob body hex socket.
  2. Next, fit the cap. Fit in one of the three hooks.
  3. Push in the remaining two hooks to finish the process.

For female screw knobs, pay attention to the male screw tightening dimensions (Bd dimension of the drawing). The cap may come off.
