Even with using theses, I say only torque to 37inlbs still,
Even though you have a stronger key bolt that withstand more torquing force, your still at the mercy of the key metal hardening that you are torquing against, and since a great deal of the commercial keys are less than perfectly hardened, over torquing leads to penning through the key case hardening surfaces, ending up with the key bolt loose over time from front to back movement shearing force instead.
Hence, the new increased torque levels are due to stronger key bolts, and the keys being hardened correctly per the new mil specs, while over does not make it back over the commercial world of lower quality parts (that have not been QC lot inspected and pass a min of three different testings).
Regarding lot testing for Mil-spec parts being sold to the government, once by the manufacturer, once by the supplier, then once more my the goverment when they receive the lot of parts. It the goverment finds the lot not acceptable (fails testing), the entire lot is rejected and sent back (all at the cost of the supplier, and depending on the supplier, may find it way on to the commercial market instead).
