Common Fastener Label Definitions
"Stainless Steel" - With the addition of 12% chromium to iron, stainless steel is formed. The chromium protects the iron against most corrosion or red colored rust; thus the term "stainless steel". The ability of stainless to form a thin layer of protection on its outside surface, called a "passive film", is its most important characteristic in preventing corrosion.
"18-8" - 300 series stainless steel having approximately (not exactly) 18% chromium and 8% nickel. The term "18-8" is used interchangeably to characterize fasteners made of 302,302HQ,303,304,384, XM7, and other variables of these grades with close chemical compositions. There is little overall difference in corrosion resistance among the 18-8 types, but slight differences in chemical composition do make certain grades more resistant than others against particular chemicals or atmospheres.
Tensile Strength - A common measure to compare the strength of a fastener. It is the load needed to pull the fastener apart.

I keep an assortment of sheet metal self tapping screws on hand because we use them frequently and its much easier and convenitnt to just go to the fastener drawer than have to make a run to the hardware store. These screws are well made, strong and function for us very well in all applicaitons.

I am disappointed that these Screws are all rusting. Description said they were stainless steel. Will have to replace and or paint all the screw heads.
