Sully2, if only you knew half as much as you think you know. How much force does it take to shear off a #6 screw?...Well Mr. Knowledge, there are a LOT of factors, I don't know them all so I will list the obvious ones. Material composition, Material Hardness and of course the most obvious "METAL FATIGUE is the progressive and localized structural damage that occurs when a material is subjected to cyclic loadings."-Wikipedia.
In case you cant understand that I will sum it up for you
Not all screws are created equal, and regardless of what they are made of they WILL ALL FAIL eventually. That being said with an intregal recoil lug such the ones that NF, BO, etc.. machine into their bases, a large portion, if not all of the "cyclic loadings" (depending on the fit) are now transfered to the base itself and not the screws and that base can take a hell of a lot more abuse than a little screw.
I know you are a simpleton, however I believe you should be able to understand this. I had my 2 year old proof read this and it made sense to her...
