China Open End Flat Head Knurled Body Rivet Nuts Manufacturers, Suppliers

Open-End Knurled Rivet Nuts (often referred to in the US as Nutserts or Threaded Inserts) are designed to provide high-strength, permanent threads in thin or soft materials where tapping is not possible.

Key Performance Features
Enhanced Torque Resistance: The knurled body bites into the host material, providing significantly higher resistance to "spin-out" (turning inside the hole) compared to smooth-body inserts.

Versatile Hole Compatibility: These inserts are engineered to provide superior grip in both punched and drilled holes, ensuring a secure fit even if the hole has slight irregularities.

High Load Bearing: The flat head design provides a large bearing surface, which reinforces the hole and increases pull-out strength, making it ideal for heavy-duty applications.

Optimized for Soft Substrates: While effective in metal, the knurled ribbing is specifically beneficial when installed in softer materials like aluminum, plastics, or fiberglass.
