What is a Steel Fastener? It is a metal screw with a threaded stud. These fasteners are used in many industrial applications. The most common uses for these fasteners include furnace parts, high temperature containers, equipment, and aircraft. These screws have a thread depth of less than a type-A screw. They feature a chamfered surface and a large head for easy threading.
The type of steel fastener depends on the intended application. Usually, fasteners are selected based on mechanical properties, cost-efficiency, and post-fabrication treatment. For critical applications, however, the fastener should be corrosion-resistant. If this is the case, a corrosion-resistant material must be used. A corrosive-resistant steel fastener is a good choice. This is due to the fact that stainless steel is stronger than aluminum.
Carbon steel is the most common type of steel used for fasteners. Carbon steel comes in grades 2, 5, and 8, with alloyed steel being at the upper end. Carbon steels range in mechanical strength from fifty to 300 ksi. It is available in both metric and inch sizes. Grade 2 is the least expensive steel and is highly workable. Most steel grade fasteners are made of this type of steel. If you're shopping for stainless steel, be sure to check ASTM Specification F593.
Stainless steels are non-magnetic and can be treated with various surface treatments. Some of these coatings are zinc, galvanized, or chrome-plated. Stainless steels are an alloy of low carbon steel and chromium and offer enhanced corrosion resistance. Stainless steels are durable and will not lose their resistance even after being scratched during installation. A nut or bolt may even become magnetized! That is why a stainless steel fastener is recommended for certain applications.
A steel fastener's corrosion resistance is determined by the chromium content. Stainless steel contains a minimum of 10.5% chromium, which makes it more resistant to corrosion and staining. Additionally, many types of stainless steel fasteners contain other elements, including copper and molybdenum. For example, A2 stainless steel fasteners are commonly used in the hospitality and medical industries. These fasteners are also sometimes called Type 304 stainless steel.
If you're looking for a stainless steel fastener, be sure to check the grades. There are several stainless steel grades, including 304, which is the most common. These grades are perfect for environments with high corrosion susceptibility. 316 stainless steel offers superior resistance to oxidation. This makes it an excellent choice for a variety of applications. The following types of steel fasteners are popular for industrial settings. These materials are extremely strong, but they must be selected carefully.
The proof load is the weight of the load at which the fastener deforms permanently. Under enough force, steel will stretch. A low force will cause it to regain its shape, while a high one will permanently deform it. The yield strength is the minimum weight required to permanently deform a steel fastener. This value is reflected in the ASTM specification. The final shaft length will also determine the strength of the steel fastener.
