12 Point Flange Nuts

Delta Fitt Inc. is a top 12 Point Flange Nuts Manufacturer that provides the best quality fastening solutions in high strength and precision. These 12-point flange nuts have an exclusive design in a form of a double-hex which offers superior distribution of torque and easy engagement of the wrench in a narrow space. Constructed using high quality materials like stainless steel, alloy steel, carbon steel and specialty alloys, they offer excellent services in high-pressure and high-temperature conditions. Their built-in flange is a washer that provides a level distribution of load and better grip, which makes them applicable in automotive, aerospace and in the heavy machinery industry.


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.

Frequently Asked Questions

Can 12 Point Flange Nuts be reused?

Yes, they can be reused in many applications, especially if not over-torqued or exposed to extreme wear. However, repeated use may wear down serrations or damage threads, reducing performance. For critical applications, it's best to assess torque retention or follow manufacturer guidelines for reuse. Some industries, like aerospace or defense, recommend single-use for maximum reliability and safety.

How durable are 12 Point Flange Nuts in high-vibration assemblies?

These nuts are specifically designed to resist loosening caused by vibration. The integrated flange and precise 12-point profile help maintain clamping force over time. Serrations on the flange further enhance grip by biting into the mating surface, preventing rotation. This makes them highly durable for use in machinery, transport, and aerospace, where vibration and movement could otherwise compromise joint integrity.

Are 12 Point Flange Nuts suitable for high-temperature or corrosive environments?

Yes, especially when made from stainless steel or coated with corrosion-resistant finishes like zinc, phosphate, or black oxide. Stainless steel versions withstand harsh conditions in marine, chemical, and outdoor environments. Heat-treated alloy steel nuts retain mechanical strength at elevated temperatures, making them suitable for turbines or engine applications. Their metal-to-metal locking and structural integrity make them dependable in harsh operating conditions.
