Discover about Closed End Flat Head Knurled Rivet Nuts

Explore the Stainless Steel Closed End Flat Head Knurled Rivet Nuts from RivetGo, designed for applications needing a strong, waterproof fastening solution. These rivet nuts combine a flat head with a closed end to block water and dust, ensuring durability in challenging conditions. Crafted from stainless steel, they offer excellent corrosion resistance for long-lasting performance. Check out other closed end knurled rivet nuts: Closed End Countersunk Knurled Rivet Nuts and Closed End Reduced Head Knurled Rivet Nuts. Closed End Countersunk Knurled Rivet Nuts and Closed End Reduced Head Knurled Rivet Nuts.

Key Features

The Closed End Flat Head Knurled Rivet Nuts feature a waterproof rivet nuts design with a closed end to prevent water and dust ingress, making them more protective than open-end rivet nuts. The flat head provides a larger contact surface for better load distribution compared to countersunk or reduced head options, while the knurled body ensures excellent grip in softer materials.

Applications

Best suited for industrial rivet nuts applications, outdoor furniture, and sheet metal assemblies in harsh environments requiring waterproof sealing, these rivet nuts come in M3 to M12. Pair with our Rivet Nut Tools for easy installation.

Installation Guide

  1. Drill a hole in the material matching the specified Hole Size (H) in the Size Chart.
  2. Insert the Closed End Flat Head Knurled Rivet Nut into the hole, ensuring the knurled body aligns with the material.
  3. Use a compatible rivet nut tool to compress and secure the rivet nut, allowing the knurled body to grip the material.
  4. Thread a matching bolt or screw into the rivet nut, ensuring the bolt length does not exceed the rivet nut’s internal depth.
    Note: Ensure the material thickness falls within the specified Grip Range (e) for a secure fit.

Technical Notes

  • Ensure the material thickness is within the Grip Range to avoid installation failure.
  • The knurled body provides anti-rotation in softer materials like aluminum or plastic; for harder materials, ensure proper hole preparation.
  • Closed End design prevents water and dust ingress, making this product ideal for outdoor or marine applications.
  • Ensure the bolt length does not exceed the rivet nut’s internal depth to avoid damaging the closed end.
  • Recommended for use with stainless steel bolts to prevent galvanic corrosion, especially in humid environments.
