Fusion 360 Stress simulation - Very LOW Factory Safety near bolt holes

baddipl — Fri, 07 Apr 2023 22:59:34 GMT

Hello, I have a problem.

I am designing parts that will be attached to a mixer and I wanted to know if the outlet can handle the required load.

Parameters: M12 screws, torque 70Nm, load 100kg, material 304SS asci.

After the first simulation, I got 0.44 safety factor near bolt holes. I was surprised but okay... I reduced the load and the result was the same in the same place - 0.44 safety factor.

So I don't know what's happening. I've read some posts on forums and many people suggest ignoring the result because they are wrong.. Is it true? Should I ignore it? I am worried the material will break during the tightening screws.

Please help me. I can share link to the model via PM if You're interested to help me. I dont wanna public it here in this post.

Please check the below screen (bolts connectors are hidden)
