Guide to Essential Furniture Fittings and Hardware
Whether you are building bespoke cabinetry from scratch, repairing a sagging wardrobe, or upgrading a flat-pack unit, the structural integrity and functionality of any piece rely on the hardware hidden beneath the surface. High-grade furniture fittings turn static timber and board materials into practical, hard-wearing storage solutions. Understanding the primary categories of fittings and furniture hardware ensures your joinery projects are durable, smooth to operate, and straightforward to assemble.
Concealed and Decorative Cabinet Hinges
Hinges dictate how cabinet doors hang, swing, and close. Selecting the right design depends on the cabinet frame construction and the desired aesthetic:
- Concealed (European) Hinges: The modern industry standard for kitchen and wardrobe doors. These fit into a standard 35 mm drilled recess (hinge cup) on the back of the door. They offer multi-way adjustment (up/down, left/right, and depth), allowing you to align door gaps perfectly after installation. Available in full overlay, half overlay, and inset configurations.
- Soft-Close Hinges: Featuring integrated hydraulic dampers, these prevent doors from slamming, reducing mechanical stress on fixings and cabinet carcasses over time.
- Butt and Decorative Hinges: Frequently used on traditional face-frame units or solid timber furniture where exposed metalwork is part of the visual character.
Smooth Drawer Runners and Slides
Drawers carry substantial weight and experience constant friction, making runner selection crucial to longevity. Core types include:
- Roller Runners: Bottom-mounted slides using nylon wheels. These are cost-effective, easy to fit, and suitable for lightweight domestic drawers.
- Ball Bearing Slides: Side-mounted runners offering higher load capacities, smoother travel, and full extension options so you can access the very back of the drawer box effortlessly.
- Undermount Runners: Concealed beneath the drawer base, providing a clean appearance on bespoke wooden drawers. These commonly feature integrated soft-close or push-to-open mechanisms.
Structural Connectors and Cam Locks
Rigid cabinet construction requires reliable joinery fittings for furniture that keep carcasses square under load. While traditional joinery uses dowels and glue, modern modular designs frequently employ mechanical connectors:
- Cam and Dowel Fixings: The foundation of flat-pack construction, allowing quick assembly and disassembly without damaging panels.
- Confirmat Screws: Heavy-duty, single-thread screws designed specifically for particleboard and MDF, offering exceptional pull-out resistance.
- Corner Braces and Modesty Blocks: Internal plastic or steel brackets that reinforce 90-degree internal joints on plinths, frames, and shelves.
Support Fittings: Legs, Feet, and Plinths
Every free-standing unit requires stable support, particularly when dealing with uneven domestic flooring. Common options include:
- Adjustable Kitchen Legs: Plastic or metal legs concealed behind a clip-on plinth board. They allow installers to level an entire run of base units precisely using a spirit level.
- Decorative Furniture Legs: Solid wood, steel, or aluminium feet designed to remain visible, popular on sideboards, sofas, and media consoles.
- Castors: Swivel or fixed wheels for mobile furniture, available with brake locks for stability.
Handles, Knobs, and Functional Finishing
The final layer of hardware bridges practicality and style. Pull handles, bar handles, and knobs must be fitted securely with standard M4 machine screws to withstand repetitive pulling force. Additionally, cable grommets and ventilation grilles provide necessary routing for power cables and heat dissipation in home offices and media units.
Frequently Asked Questions
What is the 32 mm system in furniture hardware?
The 32 mm system is a standard manufacturing grid where shelf holes, hinge mounting plates, and runner fixings are spaced in precise 32 mm increments. This standardisation makes measuring, drilling, and swapping components straightforward across modern cabinetry.
How do I determine the right hinge crank for my cabinet?
Use a full overlay hinge if the door completely covers the front edge of the cabinet carcass. Use a half overlay hinge if two doors share a central partition wall. Use an inset hinge if the door sits flush inside the cabinet frame opening.
