Stainless Steel Screws are used in a variety of applications due to their impressive corrosion resistance. Their ability to resist rust and corrosion makes them perfect for outdoor environments or any application that may be exposed to moisture. Stainless Steel Screws are also commonly used in the automotive industry as they can withstand a variety of weather conditions and other hazardous contaminants such as salt. The key to the corrosion resistant properties of Stainless Steel Screws lies within their composition, which is an iron-based alloy with added chromium and other metals such as nickel, copper and molybdenum.
The chromium in these types of screws and fasteners acts as a natural barrier to oxidation. While Stainless Steel Screws are not completely impervious to oxidation, if the material does become damaged, a naturally occurring oxide layer will form over time that protects the steel beneath. Stainless Steel Screws are a popular choice for outdoor use as the oxide layer is protected by rainwater, which will wash away any contaminants that settle on the surface of the screw.
In addition to their durability, Stainless Steel Screws offer an array of other advantages. For example, they can be used in a variety of head types and are often a preferred choice for applications that require thread cutting or tapping. They also feature a high load-bearing capacity, meaning they can hold fast and strong when tightened properly.
Another benefit of Stainless Steel Screws is that they are weldable, which is ideal for applications such as joining stainless steel panels together or creating custom attachment points. However, when used in conjunction with aluminum sheet, care should be taken, as galvanic corrosion can occur between these two materials. Stainless Steel Screws are also available in a variety of grades, including 304 and 316. Grade 316 is a corrosion resistant option that features a higher molybdenum content, which provides additional protection in environments with sulfurous or chloride-based solutions.
If you are planning to use Stainless Steel Screws in an environment where the availability of oxygen is limited, such as underwater, it is a good idea to consider using galvanized screws instead of stainless steel ones. While galvanized fasteners are extremely strong, their strength is only skin deep – the coating of hard-wearing zinc can be worn away over time, leaving the steel beneath vulnerable to corrosion. Stainless Steel Screws, on the other hand, are fully protected by their inherent chromium composition and will only corrode if they are exposed to water that is rich in oxygen.
Stainless Steel Screws are available in a wide range of head styles, lengths and diameters to suit any application. They can be purchased in a variety of packaging options, such as bulk or individual bags, and they are available at most hardware stores and home improvement centers. Despite their numerous benefits, it is important to note that these fasteners are more expensive than their counterparts made from other materials. While the extra cost may seem like a drawback, the long-term value of the product will more than offset the initial investment.
