Hot dipped and galvanized Stainless Steel Bolts and Nuts manufacturer in India

River Steel & Alloys is a known stainless steel fasteners manufacturers in India. It is manufactured from the best quality raw materials in order to serve finest product to our customers. Bolts and Nuts are available in austenitic, ferritic and martensitic steel. It is a group of iron based alloy that contains 10-30% chromium. It has features such as high corrosion resistance, easy hardening properties, and low carbon content. Therefore it makes it highly beneficial in various industries. SS Nut Bolt is available in grades such as 301, 304/L, 316/L, 321/H, 347/H, 904L, etc. Stainless Steel Bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. There are various types of bolts such as carriage bolt, anchor bolt, u-bolt, hex bolt, j-bolt, anchor bolt, etc. It is typically used to hold materials or objects or to position objects. Stainless Steel Threaded Fasteners are used for many applications, apart from obvious strength benefits it can be taken apart after they are assembled. They are cost-efficient and available in a wide sizes range. It can be used many times in a single applications, it adds extra weight to a product. ASTM A193 fasteners cover alloy steel and stainless steel bolting materials for high temperature or high-pressure service. It is commonly utilized in petroleum and chemical construction applications. High Tensile Stainless Steel Bolts can resist larger loads compared to ordinary bolts. It applies pre-tension and transmit external forces by friction. It is increasingly used from the strength level. Two intensity levels of 8.8s and 10.9s are commonly used, with 10.9 being the most common. River Steel & Alloys is a Fasteners supplier who stocks Bolts, Nuts, Washers and threaded rod in all sizes
