ASME B18.2.2 Hex Flange Nut Manufacturer | Serrated & Smooth Flange Nuts | Inch Series Locking Nut | GFM-WCR System
ASME B18.2.2 Hex Flange Nuts (Serrated & Smooth) Manufacturer
LONGZE ASME B18.2.2 Hex Flange Nuts are engineered to provide a high-strength fastening solution that eliminates the need for separate washers by integrating a wide load-bearing base. As a foundational torque-distribution node in the LONGZE GFM-WCR System, these nuts are available in both Smooth Flange (for uniform pressure) and Serrated Flange (for enhanced vibration resistance and grounding). Precision-forged for the North American inch-series market, our flange nuts ensure superior joint integrity in automotive frames, solar racking, and heavy industrial machinery.
Optimal factory-direct assembly for high-load flange joints:
- 🔹 Primary Match: ASME B18.2.1 Hex Bolts / Flange Bolts
- 🔹 Locking Upgrade: ASME B18.16.6 (Nylon Flange)
- 🔹 Metric Counterpart: DIN 6923 (ISO 4161)

🛡️ LONGZE STRATEGIC RISK MANAGEMENT & RESILIENCE
Advanced risk mitigation for high-vibration and structural flange applications.
- Vibration Loosening: Serrated options provide "locking" teeth to dig into mating surfaces.
- Surface Scuffing: Smooth flange options protect delicate or coated mating materials.
- Torque Accuracy: Friction-coefficient control on zinc-flake coatings prevents over-tightening.
- Hydrogen Embrittlement: Strict baking protocols for Grade 8 high-tensile plated nuts.
- Standard Compliance: Cross-verification between ASME B18.2.2 and IFI-145 benchmarks.
- Material Integrity: Spectrometer analysis on every raw wire coil before cold-heading.
- Logistics: Efficient DDP/CIF handling for North American and European industrial hubs.
- SOP Management: Data anchoring in the GFM-WCR repository ensures batch-to-batch consistency.

Quality Assurance & Global Logistics Risk Control
Bridging the gap between North American structural standards and global manufacturing precision.
Q: How do you ensure serration depth is consistent for electrical grounding?
A: Reliability is our red line. We use laser-profiling on serration teeth during sample audits to ensure they "bite" through surface coatings as required. Inconsistent serrations are 100% rejected.
Q: How do you manage large-volume weight constraints for air-freight to Turkey?
A: We provide detailed volume/weight calculations (TDS-VOL) for every shipment. For air-freight, we optimize pallet sizes and use high-density cardboard to maximize space while ensuring total protection.
