Stainless Steel Hexagon Flange Nuts
Stainless steel hexagon flange nuts are a critical type of fastener used across a variety of industrial and construction applications. Designed with an integrated flange that distributes pressure, these nuts offer increased holding power and simplify load-bearing operations. Their corrosion-resistant stainless steel construction makes them highly durable and ideal for both indoor and outdoor installations.
Product Overview
Stainless steel hexagon flange nuts are characterized by a hexagonal shape and a wide flange at one end, which acts as a built-in washer. This design feature reduces the risk of damage to the parts being fastened and ensures even distribution of clamping force. The self-locking capability, especially in serrated flange versions, adds mechanical reliability under vibrations or dynamic loads.
At Flybear Fastener, we manufacture an extensive range of hex flange nuts made from high-quality stainless steel materials to meet the stringent standards of global industries.

Material Introduction & Production Process
Our stainless steel hexagon flange nuts are commonly engineered using grades such as A2-70 or A4-80 stainless steel, offering high tensile strength, resistance to atmospheric corrosion, and suitability for marine environments.
Production steps include:
- Raw material bar cutting
- Cold/Hot forging (depending on size)
- Thread rolling or tapping
- Flange shaping (with or without serrations)
- Heat treatment for strength enhancement
- Surface finishing such as passivation or polishing
- 100% dimensional and visual inspection
Applications in Key Industries
These flange nuts are widely employed in:
- Automotive industry (engine mounts, suspension)
- Construction hardware (steel frames, HVAC)
- Machinery equipment fastening
- Electrical systems and enclosure assemblies
- Marine applications requiring corrosion resistance
Being vibration-resistant and able to secure loads without the need for separate washers, stainless steel hex flange nuts are indispensable components in high-performance assemblies.
