I'm trying to understand the bolt charts.
55,000 lbs before that little bolt will pull apart?

Thanks in advance

The tension-applied load that a fastener must support without evidence of deformation. Proof load is often used interchangeably with yield strength. Proof Loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread.
