Hi, I let you check this Q/A which might help you: /forum/discussion/comment/94857#Comment_94857
Then if you need more material data or stress-strain curves to use in your numerical analysis without doing a multilinear curve modeling, you can have a look into Granta EduPack or Granta Selector databases: https://www.ansys.com/products/materials/granta-selector.
Especially for the bolt, we have specific database for that.
