Product description

  • The back panel can be removed and reattached more easily and without damage,-e.g. when moving house
  • The large screw head increases contact pressure
  • Disc head without lens (the screw does not protrude)
  • Simple, gap-free connection
  • No pre-drilling required
  • Higher pull-out resistance than a nail

The universal screw is the absolute all-rounder in SPAX's range. It can do almost anything - for example, screw into softwood such as spruce and pine completely without pre-drilling, or into wooden panels such as MDF, chipboard and OSB boards. Our universal screw shows its superiority especially in interior and furniture construction, but with suitable corrosion protection it can also be used outdoors.

Thanks to its special thread geometry, the resistance when screwing is significantly lower than with conventional screws, which not only protects your muscles and nerves, but also the battery of the cordless screwdriver. Splitting of the wood close to the edges is reliably prevented.

That means for you: you turn in more screws per battery charge and you no longer have to worry about split edges.
