- TL;DR Summary
- I’m trying to mathematically show what the minimum number of threads needed to support a certain weight is.

Hello All,

I know there are rules of thumb and thread engagement calculators online but I am trying to find mathematically what the minimum number of threads acceptable would be.

I currently have an eyebolt that will be torqued to a specific value. This eyebolt setup will then need to lift a specific weight.

How can I show that the number of threads of engagement that I have in my setup is acceptable?

I know the material and properties of the bolt, plate the bolt is threading into, the torque that the eye bolt will be tightened to, and the weight of the system. I also know how many threads of engagement I currently have.

I’ve struggled to find online a good example of what I am trying to solve for.
