I have a broken chair but i love my dining set and i wanted to keep it , after a little search on good old google
it was recommended to use some of these threaded insert nuts and had a little look on Amazon and found these little beauties by ESDInCtl
perfect for us and will be able to use them for other things in the future as they are good quality but their are also
100 different size peices for different jobs , in a plastic case too which is handy as i won't lose them in the shed or have to sort through
my pot of screws ive had to put them in with , you get M4 ,M5,M6 ,M8 and M10 made of zinc alloy,
perfect for all little diy jobs .
