Hex Weld Nut

🔩 Hex Weld Nut

(High-Strength Weldable Nut for Permanent Threaded Joints in Metal Structures)

Neo Fasteners supplies precision-manufactured Hex Weld Nuts, designed for permanent, high-torque threaded connections in structural steel, fabrication, and automotive assemblies. These nuts are specifically made for welding onto metal surfaces, offering a secure and tamper-resistant threaded anchor ideal for industrial and heavy-duty applications.

🔹 Product Overview:

Hex Weld Nuts feature a standard hexagonal body with weldable projections or pilot points, allowing them to be securely fused to a base metal surface. Once welded, they provide a strong internal thread for bolts or screws, especially where access to the rear side of the material is limited. These nuts are widely used in automotive frames, construction brackets, enclosures, heavy machinery, and fabricated metal parts.

🔹 Key Specifications:

• Nut Type: Hexagonal Weld Nut
  
  

• Design Variants:
  ▫ Plain Hex Weld Nut – for surface welding
  ▫ Projection Weld Nut – with 3 or 6 weld nibs for uniform heat concentration
  ▫ Pilot Weld Nut – with extended base for locating into holes
  ▫ Recessed Base Weld Nut – for flush surface alignment
  
  

• Thread Types:
  ▫ Metric: M4 to M20
  ▫ Inch: 1/4" to 3/4" UNC / UNF / BSW
