Sumit Impex is a reputable manufacturer and supplier of high-quality stainless steel bolts suitable for a variety of industries, including construction, marine, automotive, and chemical processing. Stainless steel bolts are made of iron, containing at least 10.5% chromium. The word “stainless” refers to their capacity to withstand rust and corrosion, making them perfect for harsh situations. Our products include SS eye bolts, which are ideal for lifting and securing big objects. As one of the leading stainless steel eye bolt manufacturers, we prioritise safety and quality. We also offer stainless steel cup head bolts, which have a smooth appearance that is both stylish and useful, making them ideal for furniture and structural applications.

Sumit Impex is a Supplier of Stainless Steel Bolts, Biggest Stockist of SS Bolts as per Standards in Mumbai, India.

Best Types of Stainless Steel Shoulder Bolt, Stainless Steel Hex Bolt, Stainless Steel Flange Bolt, Stainless Steel U Bolts, Stainless Steel Eye Bolts, Stainless Steel Allen Bolt, Stainless Steel T Head Bolt, Stainless Steel Jack Bolts, Stainless Steel Square Head Bolt.

We also have 5/16 stainless steel flange bolts that are great for tight connections in high-pressure situations. When under stress, they hold tight just like they’re supposed to; these bolts are essential for DIYs and vast industry work. Stainless steel also has added elements such as nickel and molybdenum added to resist corrosion and heat. With many sizes and shapes available, a stainless steel nut and bolt can be used in a lot of applications as well. Stainless steel bolts are known for their tensile strength, which makes sure that they are safe & reliable in critical situations. Our SS bolts can withstand heavy loads, and our 18 8 stainless steel bolt strength has the capability to resist breaking. At 1 4 20 stainless steel bolt shear strength, these bolts will not fail through sideways forces.

A stainless steel 316 bolt is one of the strongest materials available. It is highly resistant to corrosion, especially in salty settings. For increasingly tougher applications, we recommend high-strength stainless steel grades like A286 and 17-4 PH. These materials are strong and long-lasting, making them ideal for difficult jobs. Austenitic stainless steel bolts have significant quantities of chromium and nickel. This type is often nonmagnetic and has excellent corrosion resistance, although it cannot be toughened with heat. Their as-rolled tensile strength ranges between 75,000 and 105,000 psi. Martensitic bolts that have been heat-treated contain 12%–18% chromium and can be toughened to tensile strengths ranging from 70,000 to 145,000 psi.
