Rdw machine parts?

I'm in Fortnite Save the world on mission to arms. There you have to find 7 machine parts. But I only find mechanical parts or screws. Can somebody help me?

I can help you with this.

To do this, you must first reach a certain level and destroy all sorts of technical equipment in cities or factories.

I've already done that, but I just do not get any machine parts.

Check it out this evening. OK?

I'm coming to the stone forest 7/8 to the weapons mission also not further

Unfortunately, I'm not getting any further…
