Nuts & bolts 101

[CompClassics]

I am revisiting this post as a new client just recently brought in his 600+HP 4000 CSX Continuation Cobra for a check up and have some routine maintenance performed. While inspecting the Cobra I found the same issue as the Cobra from the original posting, inferior hardware and the lack of understanding the proper use of fasteners in the first place. All of the inboard half shaft fasteners were loose. I am beginning to think that maybe people assembling these cars and the performance potential of these cars should require some kind of competency certification similar to an aircraft AP license, there's just to much at risk when these cars are unleashed and something goes wrong. Home many here have seen the carnage after a half shaft fails?
Here are some photos from the current Cobras previous assembly methods and the corrections taken. Please remember that when using any fastener that you should have at least three complete threads protruding from the assembly after fastening.
