We have been there.....
- Returned from shopping and quickly putting the kit together;
- We care to read the Assembly Instructions..(after a while);
- Searching the parts - but which is M4 and which is M5?!..
To All partners: ..please; If you want to prevent this at you home - just order this part and put it in the toolbox. He will be grateful, but he will never admit it. Never talk about it.
It's easy to measure the bolt size, just place the bolt as the back and see where it fits.
Enjoy your new furniture!..
