Our GB13681 M8 Hexagonal Projection Weld Nut represents the pinnacle of precision fastening technology for industrial applications. Manufactured to exacting GB13681 specifications, this M8 threaded nut features a unique three-projection design that ensures optimal current concentration during welding operations. The carefully engineered projections create consistent fusion points while minimizing thermal distortion to base materials, resulting in exceptionally clean welds with reduced energy consumption.

 

Advanced Technical Specifications

• Compliance Standard: GB13681 Full Compliance
• Thread Specification: M8 × 1.25 mm Pitch (Metric Coarse)
• Material Science: Carbon Steel Grade 45 (ML35 Equivalent)
• Surface Technology: Trivalent Chromium Plating (RoHS Compliant)
• Hardness Rating: 90-120 HV (Post-Weld Integrity Maintained)
