Essential Tool Kit for Self-Assembly

What you need to assemble a kitchen or cabinet furniture yourself: the bare minimum, what makes the job easier, and what you really shouldn't start without.

The bare minimum

  • Cordless drill/driver: the core assembly tool. Cordless is better than corded — no trailing lead
  • PZ2 and PH2 bits: for confirmat screws and euro screws — the most common fasteners in flat-pack furniture
  • Hex keys (Allen keys): for cam locks and hinge mounting plates
  • Spirit level 60–80 cm: for setting cabinets level and plumb
  • Tape measure 5 m: marking out and checking gaps
  • Rubber mallet: for seating dowels and joints without damaging the surface
  • Cross-head screwdriver: for fine hinge adjustment

What makes the job much easier

  • Laser level: projects a horizontal line across the full wall — wall units go up straight first time
  • Confirmat bit (7 mm hex): faster than using a hand key
  • Clamps (2–4): hold the carcass together while all fasteners are tightened
  • Drill with hammer mode: for wall plugs behind wall units
  • 6 mm or 8 mm masonry bit: depends on the wall plug supplied
  • Masking tape: temporary labelling of parts and surface protection

Drill/driver: what to look for

  • Torque: at least 30 Nm — sufficient for confirmat screws in chipboard
  • Two batteries: one working, one charging
  • Reverse: essential — you will need to undo things
  • Variable speed: low for screws, high for drilling
  • Brands: Bosch, Makita, DeWalt — reliable. Budget and adequate: Ryobi, Einhell

Fasteners you'll encounter in a kitchen

  • Confirmat screw: the main carcass joint. Needs a 7 mm hex pilot hole
  • Minifix / cam lock: quick-connect without a key — common in flat-pack
  • Wooden dowel: aligns parts before assembly
  • Wall plug: metal or plastic depending on the wall material
  • 3.5×16 mm screw: for fixing the back panel (HDF)

Working without a laser level

A spirit level and a chalk line can substitute if you don't have a laser.

  • Find the datum point: the highest corner of the floor — measure all base unit heights from here
  • Strike a horizontal line on the wall at the required height using a pencil and spirit level
  • Wall units: hang the first one level, then align all others to it

The most common self-assembly mistake: overtightening confirmat screws. The chipboard splits and the fastener loses its grip. Tighten to resistance, then half a turn more — no further.

What you genuinely can't do without

  • No drill/driver: confirmat screws by hand are possible, but 40–60 of them on a kitchen becomes a real ordeal
  • No level: cabinets will be crooked — it's immediately obvious and can only be fixed by taking them down again
  • No mallet: dowels hammered in by fist will damage the chipboard edge every time

What to rent rather than buy

  • Laser level: for a one-off assembly, hiring from a tool shop is cheaper than buying
  • Hammer drill: if the walls are concrete and there are many plugs to drill
  • Mitre saw: if cornice or plinth needs cutting to length
