Wing screw has a wing-like projection from the head of the screw, ideal for thumb and forefinger leverage in turning. Ensures rapid assembly and disassembly using only your hand. Ever Hardware provides the custom-made large plastic screws 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 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. Alternative 300-series grades can contain up to 7 percent molybdenum. They provide even better chloride resistance, but such heavy-duty resistance is only necessary in industrial or high concentration exposure conditions.
Both 304 and 316 stainless steels (as well as other 300-series grades) use nickel to maintain an austenitic composition at lower temperatures. Austenitic steels ensure a versatile balance of strength, workability and corrosion resistance, making them ideal for outdoor architectural and landscape applications. The benefits of stainless steel include a long service life that will retain an attractive, clean finish with low maintenance cost. It also maintains a high value if and when equipment and parts need to be decommissioned.
