🔩 Hex Weld Nut – Projection & Plain Type | For Permanent Threaded Fastening | Neo Fasteners
Hex Weld Nuts are internally threaded nuts designed to be permanently welded to another metal surface, typically for applications requiring strong, vibration-resistant fastening in sheet metal, automotive chassis, and structural components. They feature either projections for spot welding or a plain face for arc welding, depending on the application.
At Neo Fasteners, we supply Hex Weld Nuts in a variety of materials, sizes, and finishes, suitable for heavy-duty and high-strength load-bearing assemblies.
✅ Key Features
- Hexagonal shape ensures easy wrenching and strong mechanical grip
- Available with 3 or 6 weld projections for spot resistance welding
- Also available in plain base for MIG/TIG welding applications
- Creates strong, permanent threads in unthreaded steel structures
- Excellent for automation and robotic welding lines
- Allows pre-positioning before final bolt tightening
🧱 Material Options
- Mild Steel (MS) – Standard grade for automotive and industrial welding
- Low Carbon Steel – Ideal for resistance welding and robotic weld setups
- High Tensile Steel – For high-load structural components
- Stainless Steel (SS304 / SS316) – For corrosion-resistant welding applications
- Brass & Copper (On Request) – For specialized electrical applications
