When designing mechanical systems that incorporate fasteners, the clearances, c'sink depth, tap hole diameter, etc.. are needed to assure your geometries will work with the chosen fastener size. 

From the simple fastener selection to the more advanced bulk-head problems, BoltBuddy can solve most typical fastener problems... it will calculate the torque and minimum thread depth; and display the max torque and maximum tensile load available for the faster selected.
