Fastenal torque calculator?

Scouring the forums for information has quite a few questions about how much torque to use on bolts and screws. Somebody usually points out the relevant part of the online service manual that has the correct answer, but that one doesn't cover everything.

I figured Fastenal would have generic recommendations based on size and type of connector, and I checked a handful of items against the manual with fairly good success. Does anybody use this resource or have any comment on it?

Fastenal has a lab where they routine do destructive testing, they also own many subsidiaries beyond their own American and Malaysian manufacturing capacities.

Company is a bit greedy on margin and pay crap, but make no mistake the company and a lot of their resources/employees are the benchmark in the industry.

the recommendations are based on generating clamping force, and predicting the elastic/plastic range where the fastener will be rendered compromised. These predictions are quite accurate due to the tight tolerances kept when mixing alloys to achieve different grades.
