Essential Kitchen Fitting Supplies for Cabinets
Installing a new kitchen or refurbishing existing units involves far more than simply positioning carcases against a wall. The strength, longevity, and everyday functionality of any cabinetry rely entirely on the components holding everything together. Whether you are a professional fitter or a confident DIYer tackling a renovation, having the right kitchen fitting supplies ready before you begin saves time and prevents costly mistakes on site.
Carcase Assembly and Carcase Joining Fixings
Rigid cabinet assembly is the foundation of any reliable kitchen. While flat-pack units often come with basic dowels, professional installations typically require heavy-duty fixings to secure multiple units together into a continuous run.
- Connecting bolts and sleeve nuts: Usually M4 or M6 threaded steel fittings used to draw adjacent carcases tight together through pre-drilled 5 mm or 8 mm holes.
- Confirmat screws: Coarse-threaded, heavy-duty screws designed specifically for particleboard and MDF, offering significantly higher pull-out resistance than standard wood screws.
- Angle brackets and corner braces: Useful for internal bracing and securing worktop rails to unit sides.
Cabinet Hinges and Mounting Plates
Cabinet doors take the brunt of daily wear and tear. Selecting the correct cabinet hinges ensures doors hang straight, close smoothly, and remain aligned over years of use.
The industry standard for modern cabinetry is the 35 mm concealed cup hinge. When calculating your hardware requirements, consider the following:
- Opening angle: Standard installations use 110-degree hinges, but corner units, pantry units, or cabinets with internal drawers often require wide-angle hinges (up to 165 or 170 degrees) to allow unobstructed access.
- Crank and overlay: Choose full overlay for outer end panels, half overlay (cranked) for shared intermediate panels, and inset hinges for doors fitted flush inside the carcase frame.
- Soft-close mechanisms: Integrated soft-close pistons prevent slamming and reduce strain on fixing screws.
- Mounting plates: Standard cross-shaped or linear plates with cam-adjustment make vertical and lateral alignment straightforward.
Drawer Runners and Box Systems
Kitchen drawers carry considerable weight, from heavy cast-iron cookware to stacks of ceramic plates. Replacing worn runners or choosing the right hardware for new builds is crucial for smooth operation.
| Runner Type | Extension | Typical Application |
|---|---|---|
| Ball-bearing slides | Full extension | Side-mounted, cost-effective for internal trays and utility drawers. |
| Undermount runners | Single or full extension | Concealed beneath the timber drawer box, offering high weight ratings and soft-close. |
| Metal box systems | Full extension | Double-walled steel sides with integrated runners and tool-free front adjustment. |
Cabinet Legs and Plinth Clips
Floors in British homes—especially older properties—are rarely completely flat. Adjustable plastic cabinet legs allow you to establish a perfectly level datum line across an entire run of base units.
Standard kitchen legs provide height adjustment (typically ranging from 100 mm to 150 mm). Once the units are levelled and secured to the wall, plinth clips are fitted to the kickboards. These clips snap directly onto the legs, holding the plinth firmly in place while allowing easy removal for plumbing or electrical maintenance beneath the cabinets.
Wall Hanging Brackets and Rail Systems
Wall units must be mounted securely to withstand heavy loads of crockery and glassware. Modern installations rely on adjustable hanging brackets rather than simple screw fixings.
Internal concealed brackets hook onto a metal suspension rail fixed to the masonry or timber studs. Two adjustment screws inside the cabinet allow you to tweak the height and depth of the unit independently, ensuring the top units sit perfectly flush against the wall and align precisely with adjacent cabinets.
Task Lighting and Finishing Hardware
The final phase of cabinet fitting involves functional finishing touches. Under-cabinet LED lighting provides essential task illumination over worktops. Surface-mounted aluminium profiles or slimline puck lights can be neatly wired through pre-drilled cabinet panels, with cable grommets used to tidy wire routes through shelves and carcase backs.
