It is the purchase of an AHK in the house. Now I have seen with some suppliers a rigid AHK, which is however at the bottom of the support with 2 screws attached. Like e.g. here on the picture: BILD But now these AHK models are considered as rigid / not removable. I mean it is clear that one cannot remove these without appropriate tools – whereas with the detachable this is usually possible with bare hand. My question at the point: If I need the AHK only rarely, and ready Would it be possible to arm me with a wrench to remove the wrench? Or, if necessary, eat the screws so tight after the first tightening that you can’t be loosened?
