Stainless steel bolt A2, A4

Bolted connection is ubiquitous in industry, construction, housing and communal services and in everyday life. The stainless bolt is one of the most important types of fasteners. It is a cylindrical rod with a thread and a mounting head. It is used in combination with a nut of the appropriate thread size, washer, lock nut and other types of fasteners. Steel bolts provide a strong, reliable and easy-to-assemble connection that allows frequent disassembly and re-installation for maintenance or other purposes. 

ALFA-STAR company offers bolts made of A2, A4 steel with a hexagon head. This design is the most common and popular due to its resistance to high loads and the absence of the need for a special mounting tool: a commonly used wrench is used for connection. The execution of stainless steel bolts gives the product additional advantages, which include:

• high strength;
• resistance to high and low temperatures and their fluctuations;
• excellent anticorrosive properties;
• inability to magnetize;
• no toxicity and hygienic cleanliness.

The A2 version (AISI 304 steel, the so-called food grade) is used when operating in an environment of low and medium aggressive acids at temperatures from -200 to + 425 °C in the food, chemical, pharmaceutical industry, mechanical engineering and other industries. The A4 version (AISI 316 steel) is used to work in more aggressive environments, in seawater, chlorine-containing gases and solutions. A4 fasteners are used for connecting parts and assemblies in the branches of mechanical engineering, including shipbuilding, chemical, oil and gas processing industries and other areas. 

The fasteners we offer are of high quality, can be used in various working conditions, including heavy ones, and have a wide range of sizes. We are direct suppliers of hardware products, which ensures a low price level.
