Round head screw stainless fasteners thread forming screws
Round head screw the head with high crown and deep recess but the diameter is smaller than a pan head. For general applications and where the requirement of a smaller head OD in application. Ever Hardware provides custom made round head screw and customizable packaging.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide; and, because of the greater volume of the iron oxide, this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.
Thread forming tapping screws are generally for applications where large internal stresses are permissible, or desirable, to increase resistance to loosening. Many different thread forming screws are available to lower assembly costs by solving application problems such as eliminating the need to drill and tap panels. These can be broadly categorized into thread forming screws for metal and thread forming screws for plastic.
