Stainless Steel 440 Screw

The stainless steel 440 Screw is composed of a unique chemical alloy to ensure its strength and durability. This alloy contains chromium, iron, carbon, manganese, silicon and molybdenum in varying amounts depending on the specific application for the screw. Chromium imparts excellent corrosion-resistant properties to stainless steel, while iron provides notable strength and durability. Meanwhile, carbon and manganese help enhance the hardenability of the steel, with silicon adding even more power and non-magnetic behaviours. Finally, molybdenum provides additional creep strength, allowing it to serve in temperatures up to 845° Celsius without becoming brittle or degrading. Together, these components create a highly dependable part used in many industries.

SS 440 Screws are an incredibly versatile fastening product, popular with DIYers and professional tradespeople. A low-cost hardenable material can be used in various applications where superior strength and durability are needed. The grade 440 material gives the 435 stainless screws excellent high-temperature stability and resistance to corrosive materials such as saltwater, acids, and more. These screws are designed for simplified insertion into wood or metal surfaces without pre-drilling. Thanks to their heat treatment and excellent magnetic attraction, these stainless steel screws provide a dependable hold to keep parts firmly connected.
