The hexagon dome nut is often referred to as an acorn nut due to its shape. Additionally, they can be referred to as Crown nuts, Blind nuts, or Dome caps. It typically comes in steel, stainless steel, nylon, brass, and is cast in one piece with a cap at one end. Standard nuts are not as aesthetically pleasing as dome nuts. Stainless steel of this grade is the standard industrial grade. A2 is the most commonly used of all stainless steel fasteners. The corrosion resistance of this steel is superior to that of standard steels such as plain steel and galvanized steel. When using this type of product outdoors in a marine environment, you should consider using A4 grade (SS316). It is less likely that stainless steel will corrosion, rust, or stain when exposed to water as it does to ordinary steel. The material is not fully stain-proof when the ambient oxygen level is low, the salinity level is high, or the air circulation is poor. It is possible to find different grades of stainless steel and a variety of surface finishes according to the type of environment in which the alloy will be used. There are situations in which stainless steel is required because it has both high strength and corrosion resistance properties. Stainless steel A2 is often referred to as stainless steel 304 or 18/8. As the name implies, 18/8 refers to the amount of chromium and nickel in the alloy. About 18% chromium and 8% nickel are contained in the alloy. Steel A2 (304, 18/8) has a non-magnetic composition and is an austenitic steel. In addition to providing corrosion resistance, the chromium also provides oxidation resistance, however it can also tarnish. In addition, it is resistant to a wide variety of inorganic chemicals as well as most organic chemicals and sterilizing solutions. Therefore, this material is extensively used in sinks, table tops, stoves, refrigerators, pots, pans, dairy equipment, brewing plants, fruit farms, food processing plants, dye tanks, and pipelines, among other applications. Among austenitic stainless steels, type 304 is the most versatile and widely used due to its chromium-nickel content and low carbon content. These alloys are all modified forms of the 18% chromium, 8% nickel austenitic alloy in addition to being resistant to oxidation and corrosion, type 304 is also durable and long lasting. Each of these alloys provides ease of fabrication and cleaning, prevents contamination, and provides a variety of finishes and finishes. We advise A4 stainless steel if your applications calls for a marine grade stainless steel. WE AUTOMATICALLY USE HERMES (2 – 3 DAYS) FOR THESE PACKS.
