Tool-Free 3D Adjustable Concealed Hinges for Cabinets
The WD06-12HA is a premium three-way small-angle door hinge designed for full overlay cabinet doors, offering 3D micro-adjustment (height, depth, and lateral) for perfect door alignment. Engineered for precision, it features a smooth hydraulic closing action and 105° opening angle, ensuring quiet, effortless operation. The heavy-duty zinc alloy construction provides durability, while the integrated soft-closing mechanism prevents slamming. Ideal for modern kitchens and furniture, this hinge supports 16-23mm thick doors and accommodates various cabinet styles. Its tool-friendly adjustment screws simplify installation and fine-tuning, making it a top choice for professional cabinet makers and DIY enthusiasts seeking reliable, high-end hardware.
At the heart of their performance is a dual-ball bearing system with 12 high-precision steel balls per hinge, reducing friction to 0.03N/mm for effortless door movement. The copper damper piston absorbs impact energy during closure, ensuring smooth, silent operation and extending hinge life to 150,000 cycles—equivalent to 20+ years of daily use. This engineering minimizes wear on both hinges and cabinetry, reducing the need for replacements or repairs over time.
Tool-Free Installation
Designed for convenience, the clip-on design snaps securely into pre-drilled cabinet holes (35mm diameter), eliminating the need for screws during initial installation. Adjustment levers (4mm diameter) allow fine-tuning of door alignment without tools, with clear markings for easy adjustment. This user-friendly design reduces installation time by 70% compared to traditional hinges, making it accessible for DIY enthusiasts and professionals alike. Whether installing new cabinets or retrofitting existing ones, the process is simplified with no specialized tools required.
Heavy-Duty Durability
The hinges undergo 1,000-hour salt spray tests (per ASTM B117), with a zinc-nickel plating (8μm thickness) that provides superior corrosion resistance, even in humid environments like bathrooms and kitchens. Triangular reinforcement plates (2mm steel) distribute weight evenly across the hinge mount, preventing sagging or door misalignment over time. This robust construction ensures the hinges maintain their performance in high-traffic areas, from busy kitchen cabinets to frequently used office storage.
Universal Compatibility
Versatile enough for most cabinetry, they fit cabinet doors 16–22mm thick with universal mounting plates (60mm x 40mm) that adapt to various cabinet styles, from frameless to face-frame designs. Compliant with EN 1935 standards, they meet strict European quality and safety requirements, ensuring reliable performance in both residential and commercial applications. This universal design makes them a go-to choice for contractors, cabinet makers, and homeowners.

Hinge Installation Guide for Enhanced User Experience
Prepare Tools and Materials
Gather a drill, 35mm Forstner bit, pencil, tape measure, screwdriver, and the WD06 - 12HA hinges. Ensure all parts are intact.
Mark Drilling Position
Use a tape measure to mark the center of the door edge for the cup hole. The door drilling distance (k) should be 3 - 7mm from the door edge. Draw clear lines with a pencil.
Drill the Cup Hole
Set the drill with a 35mm Forstner bit. Align it with the mark and drill to a depth of 11.5mm (match the cup depth). Keep the drill perpendicular for a clean hole.
Install Hinge Cup
Insert the hinge cup into the drilled hole. Secure it with the provided screws using a screwdriver. Ensure it’s flush and stable.
Attach Hinge Arm to Cabinet
Position the hinge arm on the cabinet side panel. Use screws to fix it, making sure it’s aligned with the door’s cup hinge.
Adjust for Alignment
Utilize the 3D adjustment feature. Tweak vertical, horizontal, and depth positions (as per the 3D adjust specs) to ensure the door sits perfectly, with even gaps and smooth opening/closing.
Test Operation
Open and close the door multiple times. Check if it opens to the max 105 + 3° angle smoothly and closes quietly without misalignment.
