I have a question regarding bolt strength!

Thank you. It would be great if you could tell me the standards so I can check them myself, hehe

What are the standards for strength calculation? Could it be expressed in more detail?

Calculation of the maximum shear stress that a bolt can withstand and calculation of the maximum tensile and compressive stresses
