Contractor friend is trying to find the ultimate forces for one of these screws (3/8" diameter) screwed all the way into 5/8" A36 steel plate. I can't find any charts or values and don't know the ASME spec.

He needs it to prove to client that he can meet a blast force, they are doing a hardening of a building.

If he has the screw model # used then he can calculate the shear and tensile forces on the screw shank (diameter excl threads) per AISC for the given steel material. The tensile strength of threads pulling out would be unknown though....
