Flange Nuts

Our flange nuts feature a wide, built-in flange at the base that acts as an integrated washer, spreading the clamping load and eliminating the need for a separate washer in many applications. Available in metric sizes with a serrated or smooth flange face.

Flange nuts are particularly useful in automotive, mechanical, and structural applications where vibration resistance and quick assembly are important. Available in BZP and HDG finishes to suit indoor and outdoor use.

  • Sizes: M6, M8, M10, M12
  • Integrated flange — no separate washer required
  • Finishes: BZP and HDG
  • Metric coarse thread
  • Ideal for high-vibration applications

Not sure which finish to choose?

We stock fasteners in three finishes to suit every application. BZP is ideal for indoor and sheltered use. HDG gives heavy-duty protection for outdoor, structural, and timber work. A4 Grade 316 Stainless is the right choice for marine, coastal, and chemical environments. Read our guide to pick the right finish for your project.
