CSK Head Serrated Closed End Rivet Nuts – Steel

Flush Fit. Full Seal. Zero Compromise.

Looking for a nut insert that can handle harsh environments while keeping your assemblies sleek and secure? Our CSK (countersunk) head serrated closed end rivet nuts in steel are engineered for strength, style, and stability.

The closed-end design seals out moisture and contaminants, protecting your threads and extending service life—while the serrated flange delivers anti-rotation performance under heavy vibration. Ideal for automotive builds, steel enclosures, industrial panels, and more where flush-fit fastening matters just as much as strength.


⚙️ Why It Works:

  • Flush CSK head = smooth, snag-free finish

  • Closed end = sealed threads, corrosion protection

  • Serrated flange = maximum grip on steel

  • Steel construction = built for demanding jobs


Build it stronger. Seal it smarter.
