Carbon Steel Black Oxide Hex Flange Nut

• Carbon Steel: This is the most common material for hexagonal flange nuts. It offers good strength and durability at a relatively low cost. It is suitable for general industrial applications where high corrosion resistance is not a primary concern.

  
  

• Automotive & EV: chassis sub-frames, plastic intake manifolds, battery tray rails—black finish gives stealth appearance and avoids reflective glare.
• Motorcycle & Powersports: engine guards, exhaust shields, foot-peg brackets; flange spreads load on thin-wall aluminum tubing.
• Solar Racking: grounding clips and rail splices—serrated flange maintains electrical continuity while resisting wind-load vibration.
• Furniture & Retail Fixtures: black decorative look matches powder-coated steel or aluminum extrusions; washer-free assembly speeds line installation.
• Electronics & Server Racks: black oxide non-conductive surface prevents shorting on painted 19" rack side panels; Class 8 strength secures heavy UPS units.
• Industrial Machinery: conveyor side-frames, robot bases—black Geomet® version withstands 600 h salt-spray in food-plant wash-down zones.
• Railway & Construction: flange nut locks guard-rail bolts and vibration-dampened pads; Grade 10 or A4-80 stainless chosen for outdoor corrosion exposure.

Flanged Design: The flange provides a larger surface area, which can help prevent the nut from sinking into soft materials when tightened.

Hexagonal Shape: The hex shape allows for use with standard wrenches and is easier to grip and turn compared to other shapes.

Versatile Applications: Suitable for a wide range of applications, including automotive, machinery, construction, and general assembly.

Material Options: Commonly made from steel, stainless steel, brass, or other metals, and can be coated or plated for corrosion resistance or aesthetic purposes.
