Woot! HTTP://www.DigiPeer.de is back up and running so I am back to practicing part drawing in Inventor LT 2021. I am looking at the following drawing titled "Pin" (according to some google translate).

enter image description here

In the drawing there is a flanged shape drawn at roughly the quarter mark of the smaller shaft. However the shape is not dimensioned in anyway what so ever.

What is this?

My best guess right now is that my German translation abilities is worse than I thought and this is actually a rivet and that would be the deformed head. This my guess based on this drawing where there is a pin pattern that shows a similar flange shape in the 6.1 dia. hole. I have yet to stumble on the assembly drawing in this section.

enter image description here

Am I correct assuming this is a deformed shape symbol?

  • $\begingroup$ As "stift" can mean pin then is that a designation for a thread and given the outer diameter the details are just assumed? $\endgroup$

  • $\begingroup$ Look for a material designation. And find an assembly drawing using the part if possible. Form (there's a shape and material completes it), Fit, Function. Seek along those lines $\endgroup$

  • $\begingroup$ Scale appears to be 1:1. Measure it. $\endgroup$ Commented Jun 22, 2022 at 13:49
  • $\begingroup$ @Abel the material designation is 3355.5. Unfortunately I have no clue what that refers to. I am still on the look out for the assembly drawings as I have a series of similar drawings to the lower one and I am wondering how they stack together currently. $\endgroup$

  • $\begingroup$ @SolarMike Interesting thought on the potential of thread indicator. $\endgroup$
