Flange Nuts are available in sizes ranging from: 1/4″-20 to 3/4″-10, and finished in Zinc plating, Yellow Zinc plating, Stainless Steel or Type 316 Stainless.

Type 316 Stainless is Marine Grade quality.

What Flanged Nuts Are Good For

Flanged nuts are specialized fasteners with an integrated washer‑like flange that make them ideal for applications needing secure fastening, load distribution, vibration resistance, and easier installation.

Key Benefits

• • Load Distribution – The flange provides a larger bearing surface, spreading the clamping force evenly to prevent damage to the material and reduce the risk of over‑tightening.
  • Vibration Resistance – The flange’s locking effect helps keep the nut from loosening in high‑vibration environments, making them popular in automotive, machinery, and industrial equipment.
  • Alignment Assistance – The flange aids in positioning the nut accurately during installation, saving time and improving precision.
  • Sealing – In some cases, the flange acts as a barrier against moisture, dust, or contaminants, helping maintain joint integrity.
  • Eliminates Need for a Separate Washer – This simplifies assembly and reduces parts count.
