The B2B industry appreciates the use of 12 point flange nuts as they have better mechanical strength, a good fit, and dependability in the critical assemblies. The performance engines and turbine systems, industrial machinery, and structural components which require high-level fastening and vibration are typical applications of these nuts. Their geometry is unique, which means that they can be applied better in terms of torque and stained tightening, which will guarantee them a stable position even in the conditions of the operation that are more demanding. These fasteners remain a reliable option to companies that need durability, accuracy, and an improved fastening performance. We supply Hex Flange Nuts designed with built-in flanges to provide excellent load distribution and improved fastening stability.
