I went over the two threads you posted about engine bolts (screws). I didn't see any rules broken; unless, there were some deleted replies. We do however needed the equipment numbers we even we can look up your equipment. This so we can post snippets of parts layouts and get you using the correct terms for the parts or at least get us all on the same page (train of thought).
Also depending where you are some parts goes by different names. Just like tools can have different names for the same thing. For example here in the US we wrenches but other parts of the world they are called spanners. Even here some OEM refer items like pulleys as pulleys and others call them sheaves; same thing just different terms.
