Assembly: Wall mount for punching bag

Unfortunately, the image links did not work above, so here are the two wall anchor variants:

Thank you!!!

I have created a more detailed sketch for clarification.

Does it make sense to calculate the bending moment or to offset it with the torque of the dowels? I want to avoid another failure as much as possible... :-P

The bending moment certainly seems so "small" that I can press the flat steel almost completely flat against the wall with full muscular effort. However, I cannot estimate how many Nm of bending moment that corresponds to.

If nothing speaks against the Rawl wall anchors with external thread, i.e., with a nut, apart from the more complicated disassembly, I would now like to try these. With the other variant, I still have the concern that I may not be able to fully countersink the screws due to the bending moment and that the anchor will not set properly. Please provide feedback again.

Thanks as always!

I apologize for disregarding the forum rules, it will not happen again!

Thank you! To my knowledge, a hyphen is not a job title, so please fill in this gap in your profile Rheinische Grüße

Thanks!!!

Both are equally good. You could lock the one with external thread from the back with a nut and thus have the bracket lie flush against the lock nut.

Why is the bracket bent at all?
