There are a variety of fasteners such as nuts and bolts available in the market that are made up of various materials. Inconel Fasteners are one among those. They are one of the high strength fasteners that are made up of nickel chromium and molybdenum alloy. Inconel Bolts provide thermal stability and can be used from cryogenic temperatures to elevated temperatures of 2200 degrees C. Inconel Hex Bolts are not affected by moderate conditions. Due to this reason these fasteners are used in oil and gas generation, petrochemical, and aerospace industry.
Inconel Threaded Rod offers excellent resistance to oxidation and corrosion even at elevated temperatures. Since this series of fasteners is said to have a high fatigue strength and high tensile strength Inconel Stud Bolts are used in applications such as submarines, propulsion motors, as well as in chemical industries. M10 Inconel Studs are subdivided into various grades such as 600, 625, 718, and so on. Inconel Screws belonging to a certain grade are non-magnetic and can resist corrosion from cryogenic temperature to 2000 degrees F. while some higher range grades can be used in -423 degrees F to 1300 degrees F. Inconel Nuts also provide good resistance in carburizing and chloride containing environments.
Inconel Fasteners manufacturers in India supply these fasteners at a cheaper rate when compared to manufacturers in other countries dueto the low cost of labour available in the country. Inconel Rivets produced by us are passed through various tests which enable us to confirm the properties inherited by them. Inconel socket head cap screws do not succumb to caustic solutions and high purity water solutions. Inconel Washers are used to provide a better grip on the fastener and prevent it from becoming loose. Inconel Belleville Washers are used in engineering as they are able to maintain their structure in applications that would cause permanent distortion. Inconel Flat Washers produced and supplied by us are as per the international standards this helps us to cater to our international customers with ease.

Steel Tubes India offers products in a variety of materials, coatings, and platings, including anticorrosive Lag Bolt. Whatever your needs or the size of your order. Dry dock repairs and shipbuilding requires fasteners to fasten the corners and panels of the docks together. Shipbuilding requires Lag Bolt at every square inch on the ship's surface in order to hold the vessel together while sailing. While this may sound like simple work, these Inconel Lag Bolt often come in close contact with saline water, fungus and other natural obstacles. The fasteners not only need to withstand rusting, but also need to hinge on perfectly in presence of algae and waters plantation. At Steel Tubes India, we understand these needs and have designed our fasteners to meet the specific needs of the shipbuilding industry.
