Unsure if this link will work but worth a try for a bolt being pulled out of a wall.

Concrete wall?
At 1.32 time-slot, display reads 722 ?
122?
Kn??
... Interesting that the bolt head sheared in outward loading before the bolt pulled.

I wonder how different the number would be if impact loading was applied vs the static loading it received...
