Aluminum screws?
#16
The even bigger problem is that the material is soft. So very easy to ruin the head, with all the trubble to drill them out afterwards.
Bullshit !

Stainless steel is heavier/much denser than aluminum. Stainless is typically 2 times denser than aluminum which makes it stronger than aluminum.
With this being said. That is why I only use the stainless on high stress areas and besides, most of your touring cars are typically underweight. I'm not arguing but simply stating the facts "Aluminum vs. Stainless"

Density does not equal strength.
Many SS screws are 300 series. It's not exactly the strongest stuff. Tensile strength is approximately half that of steel at, for all intents and purposes, the same weight. 7075 Al is comparable to SS with regards to strength. Fatigue may be another issue, but I highly doubt any of the screws we use fail in fatigue. They fail when we slam our cars into a pipe or strip the head.
Given that, the only reason to use SS is for aesthetics or to add corrosion protection while maintaining weight. Thus, chassis screws may be a good application for SS screws where weight is desired. Strength is still good enough for what we're doing. Use decent tools and the heads won't strip.

Bullshit.

You made a comment against my statement about aluminum vs. stainless and my response was stating the facts regarding aluminum vs. stainless steel.
However if that's what you were referring to than I would agree, but you never made that statement to begin with. All I'm saying, "I prefer stainless steel in certain areas opposed to aluminum" and also stating true facts between those two materials. Not one time was standard steel mentioned here.

have you used the titanium screw from fastener express yet?
