Product Overview

The 71 flat-head knurled sealed rivet nut uses a flat knurled head and is installed into sheet metal by riveting; the outer knurl provides torque resistance, and after riveting the head sits flush with the panel surface while sealing against water. It suits thin-sheet structures that need a flush appearance and a waterproof threaded connection.

Technical Features

  • A flat-head design stays flush with the panel after riveting for high flatness.
  • Knurled outer circumference: good torque resistance without spinning
  • Sealing function meets water resistance requirements
  • One-step riveting, no tapping and no welding required
  • Size and thread profile customisable to drawings
