I picked up a lot of these sorts of things recently because we were doing a steampunk costume thing and needed a LOT of parts, and anything we didn't use for the costumes we can keep in the garage and use them as they're intended to be used. I can't say much about them honestly, they function both as their intended function and made great costume decoration, plenty of selection and good value for money. They're spray painted super easily, are good quality metal, and my partner tells me that they have good threads on them so he's kept a few back for workshop projects.

You get 90 rivet nuts, in a M8 size for around £7. Very good value for money. They are made of carbon steel, with a thread through the middle. Easy to install with the correct tools. Work well.
