Solid back panel fastening with Spax screws

Practical benefits
  • Wide flat flange head: The enlarged bearing surface distributes clamping force evenly across thin boards, preventing you from overdriving or damaging panels.
  • Stable T-STAR plus drive: You get direct torque transfer and eliminate cam-out issues with the exact-fitting T20 drive system during rapid installation.
  • Protective WIROX steel coating: The advanced surface treatment shields the steel core from corrosion to keep your interior furniture assemblies strong and reliable.

In a nutshell

The right choise for

With Spax back panel screws, you fasten thin rear panels and cabinet backings quickly, cleanly, and without damaging materials. The broad, flat flange head spreads clamping force evenly across thin sheet materials such as hardboard or thin MDF, preventing the screw from pulling through and eliminating the need for washers. Thanks to the t-star plus T20 drive system, torque is transferred directly and smoothly without cam-out or slipping. The full thread across the entire 25 mm length delivers maximum grip and pull-out resistance in wooden frames, while the corrosion-resistant wirox coating ensures durable, lasting hold for all interior furniture assembly.

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.

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