Stainless Steel Flange Nuts manufacturer in India produce nuts of different types. The flange nuts are special in shape and function that it has a flange attached. Suraj Metal Corporation is a leading manufacturer and supplier of the Stainless Steel Flange Nuts in different sizes and dimensions. There are different material grades that are used to produce these nuts.
The nuts have one end of it flared outward to form a flange. The flange often has serrated surface towards the bolt. The Stainless Steel Serrated Flange Nuts act as washers and at the same time to tighten the nuts together with the bolt, bolt hole and the holding surface. These flange nuts are common for applications that require High-Strength 12-Point Flange Nuts which has high tensile and yield strengths. They can withstand high torque forces and stresses. The applications include exhausts and manifolds. The Exhaust Manifold Flange Nuts can perform under high temperatures and high pressures. The use of high temperature service and high pressure service high-strength 12-point flange nuts can be seen in power generation, oil and gas and in heat exchanger and boiler class applications. There are different grades and specifications such as Metric Grade 8 flange nuts which are useful in different application types. Please feel free to contact us for more information on the different types, sizes, grades and specifications such hex flange nut din 6923 and their prices.
