Therefore, stainless steel with over-sized washers is often used for long screws for added strength and protection. Screws and bolts also differ in shape and cost — screws are often tapered, while bolts are not, and bolts tend to cost more than screws. This too is also a conservative number. and shear forces, if the bottom sheet (i.e., the sheet not in contact with the screw head) is thinner than the top sheet, tension pull-out and shear may occur. 2 CMU = 1,600 PSI minimum compressive strength with 2,000 PSI grout. Screws and screw connections have been tested per AISI Standard Test Method S904 and S905 with the exception of 22-gauge values which are based on calculations of the AISI S100. These rivets feature more girdles on top, which help in providing a more finished appearance. More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water. Fasten sheet metal up to 0.200" thick.
