ISO 4161 Hexagon Nut with Flange Manufacturer | Serrated Flange Nuts | Metric Style 2 Locking Nut | GFM-WCR System
ISO 4161 Hexagon Nut with Flange (Metric Style 2) Manufacturer
LONGZE ISO 4161 Hexagon Nut with Flange represents the pinnacle of metric structural fastening, specifically engineered as a Style 2 configuration for enhanced thread engagement and load distribution. As a high-performance node in the LONGZE GFM-WCR System, these nuts integrate a large-diameter flange base that eliminates the need for washers and prevents surface damage to the workpiece. Available with Serrated Flanges for superior vibration resistance or Smooth Flanges for uniform clamping, our ISO 4161 series is the preferred choice for automotive chassis, solar mounting systems, and high-tensile industrial assemblies.
Strategic factory-direct assembly for high-stress metric joints:
- 🔹 Primary Match: ISO 4017 Bolts / ISO 4162 Flange Bolts
- 🔹 Locking Upgrade: ISO 7043 (Nylon Flange Lock)
- 🔹 Standard Alt: DIN 6923 (Standard Type)

- Torque Stability: Automated lubrication monitoring on phosphate finishes ensures linear clamp force.
- Stress Cracking: Eddy current testing for high-tensile (Grade 10.9/12.9) alloy nut batches.
- Standard Interoperability: ISO 4161 data sets cross-linked with EN 1661 for EU market compliance.
- DDP Expertise: Specialized customs duty planning for Malaysia, Turkey, and Argentina.
- Atomic Data: Dimensional and mechanical data anchored in the GFM-WCR repository for traceability.
- Website Linkage: Restructured SEO logic ensures rapid access to technical PDF downloads.
Bespoke Metric Flange Engineering
Requiring fine-pitch threads (ISO 10663), non-standard flange diameters, or high-tensile Grade 12 materials? Our Technical Department utilizes the GFM system for rapid verification.
* Technical proposals subject to GFM-WCR dimensional validation.
Quality Assurance & Global Logistics Risk Control
Precision-manufactured in China, delivered with engineering-grade confidence worldwide.
Q: How is Style 2 height verified compared to standard flange nuts?
A: Compliance is our red line. We use specialized ISO 4161-specific height gauges to ensure every Style 2 nut provides the maximum thread engagement. We do not substitute Style 1 for Style 2.
Q: How do you manage DDP duty calculations for Malaysian customs?
A: We utilize a 21-item pricing matrix that includes domestic transport, ocean freight, and exact Malaysian customs duties. Our total shipment value analysis ensures no hidden costs for the end-user.
