Detailed Information
Prashaant Steel & Alloys is a major manufacturer and supplier of the Flange Nut. The Flange Nuts we make for use in the right kinds of environments are made with perfect accuracy and good dimensions. We at Prashaant Steel & Alloys make flange nuts from the best material, which has a high resistance to corrosion and oxidation in a variety of situations. Prashaant Steel & Alloys has a production plant that can make Flange Nuts in different sizes and lengths for large orders. Customers can also make custom orders, and we make the Flange Nut according to their needs and specifications. Because they are easy to shape, the Flange Nuts we make are used in many different industries. At Prashaant Steel & Alloys, we serve both small and large customers from all over the world industries. Because the Flange Nut is always the same, we have made a name for ourselves in the industry.
Stainless Steel Flange Nuts are just regular stainless steel nuts with a flange attached below the head. The flanged nuts have a better hold on the surface they are screwed into. When welding is needed, the flanged nuts are also a better fit for welding. There are different shapes like Hex Flange Nuts, Wing Nuts, Lock Nuts, and others that have a flange below the head. Some nuts have ends that look like cones, while others have ends that are open. The nut’s size varies from M2 to M6O in metric measurements and from % inches to 4 inches in UNC measurements.
The length of the SS Flange Nut can be anywhere from 6mm to 500mm. There are different types and methods of making these nuts, and the materials used vary in quality. Grade 8 Flange Nuts are made from austenitic stainless steel type 304 and have high tensile strength. They can handle a lot of torque, a lot of pressure, and high temperatures. These nuts can work in temperatures up to 870 degrees Celsius and have a minimum yield strength of 2ISMPa and a minimum tensile strength of SOSMPa. There are nuts that are changed or made for a specific job, like the Serrated Flange Nuts, which have teeth on the bottom of the flanges. The vibrations make it hard to loosen the nuts, but the serrations make it possible to tighten them. There are different rules about the sizes of nuts, such as DIN934, DIN439, and others. There are also a variety of heads
There are different kinds of nuts, like High-Strength 12-Point Flange Nuts, that are used for different kinds of applications.
Prashaant Steel & Alloys is a major producer and supplier of the Flange Nut. The Flange Nut that we produce for applications in appropriate environments are crafted with absolute accuracy and dimensional quality. We at Prashaant Steel & Alloys are active in the manufacturing ofFlange Nut superlative material, which has high resistivity against corrosion and oxidation under different conditions. Prashaant Steel & Alloys houses a production plant capable of processing Flange Nut bulk orders of different sizes and lengths. We also take custom orders from our customers and manufacture the Flange Nut according to their specifications and requirements. Because of their excellent formability properties, the Flange Nut that we produce are known to have diverse applications in various industrial sectors. We customers from all over the globe at Prashaant Steel & Alloys cater to both small and large industries. Thanks to the consistency of the Flange Nut we have established a reputation in the industry.
Stainless Steel Flange Nuts are regular stainless steel nuts with a flange attached below the head. The flanged nuts have higher grip on the material surface. Where welding is necessary, the flanged nuts provide better welding fit as well. There are different shapes such as the Hex Flange Nuts, wing nuts, lock nuts and others which come with a flange below the head. Some nuts have cone shaped ends while others have open ends. The size of the nut ranges from M2 to M60 in the metric size and from ¼ inches to 4 inches in the UNC dimensions.
The SS Flange Nut can come in different lengths ranging from 6mm to 500mm as well. There are different manufacturing types and production methods for these nuts with varying material grades. The Grade 8 Flange Nuts are made up of 304 austenitic stainless steel and are high tensile nuts. They can withstand high torque values, high pressure and high temperatures as well. The minimum yield strength of these nuts is 215MPa and the minimum tensile strength is 505MPa with operating temperatures ranging up to 870 degrees Celsius. There are modified or specialized nuts such as the Serrated Flange Nuts which have serrations on the bottom of the flanges. These serrations allow for the nuts to tighten in but make it difficult to be loosened due to vibrations. There are different standards such as DIN934, DIN439 and others to govern the dimensions of the nuts. There are also different head types such as the High-Strength 12-Point Flange Nuts which are used for various specific application types.

FAQ
What are flange bolts used for?
Flange bolts (washer bolts) have a flange cast into the bolt head, which acts in the same way as a washer, to spread the load over a wider area. Often used in car manufacturing, for example, this type of bolt enables much faster installation on an assembly line than a traditional bolt and washer.
What is the flange standard?
A flange standard lays down the dimensions, surface finish, facing type, marking, material, and technical specifications for flanges. National flange standards in Europe have largely been superseded by the European EN 1092 series.
