Product Description

The JINHAN JH-2112 Minifix Spreading Bolt & 3-in-1 Fast Connector is engineered for robust, concealed assembly of high-end cabinetry and modular furniture systems. Combining a cold-rolled carbon steel core with a nylon friction sleeve, this connector ensures superior pull-out strength and vibration resistance compared to industry-standard zinc alloy alternatives. Designed to pair seamlessly with Minifix cam locks, it provides an invisible fastening solution for panels ≥15mm thickness.

​​Key Features​​

• ​​Industrial-Grade Material:​​ Cold-rolled carbon steel chassis (not lightweight zinc alloy) offers ≥30% higher tensile strength for long-term structural integrity.
• ​​Anti-Slip Nylon Sleeve:​​ Reinforces grip between connector and panel, preventing loosening under dynamic loads.
• ​​True Hidden Installation:​​ Fully recessed design maintains clean aesthetic lines for premium furniture.
• ​​Corrosion Resistance:​​ Colored zinc plating (5-8μm thickness) passes 48hrs salt spray test.
• ​​Optimized Geometry:​​ Precision-engineered 40mm shaft length ensures compatibility with 15-25mm laminated particleboard/MDF.
