Stainless Steel Flange Nuts

High-Strength 12-Point/ Exhaust Flange Nuts, SS Hex flange nuts manufacturers in india

supplies a full range of Stainless Steel Serrated, lock and Metric Flange Nuts at Factory price in Mumbai, India

Stainless Steel Flange Nuts can come under different standards such as the DIN 934, 982, 985, 936 and so on. There are UNC, UNF, UNEF, UNS, NPT and NPTF standards for the thread types. Micro Metals is a leading manufacturer and supplier of the different types such as the High-Strength 12-Point Flange Nuts. The 12 point nuts are made by overlapping two hexagon shapes on the nut head.

There are different types of nuts made from different material grades. The SS Hex Flange Nuts are some of the commonly used nuts due to the geometric strength and ease of installation with tools. The materials used for these nuts can vary as 18-8 steel, 4.6,8.8, A2, A4, A2-70 and so on. The difference in the material composition makes the difference in the mechanical properties as well. The Stainless Steel Serrated Flange Nuts have serrated outer surface rings so that they do not loosen easily under vibrations. The nuts could be made of cold forging, hot forging and machining techniques with sizes ranging from M24 to M100.

The SS Lock Flange Nuts are another type that have the specific form and structure to lock onto the bolt so that they don’t come off easily. There are different techniques used to hold the nuts onto the bolts. The SS Metric Flange Nuts are used in many flanging applications such as water lines, oil and gas lines and in other pipeline applications as well. Please feel free to contact us for more information on the different types of the flange nuts and their pricing.
