Practical benefits
  • Optimal drive power transfer: The T-STAR plus T20 socket prevents bit slippage, allowing you to drive screws smoothly with complete control.

  • Strong full thread grip: The full-length thread ensures maximum holding power and high tensile strength across your wooden and chipboard assemblies.

In a nutshell

The right choise for

With the Spax chipboard screw 3.5 x 20 mm, you achieve strong and clean fastenings in wood and board materials. The t-star plus T20 drive ensures optimal power transmission and prevents bit slippage, giving you full control and fast driving. Thanks to the countersunk multi-head, the screw sinks neatly flush into the surface without requiring pre-drilling in softwoods. The full thread over 20 mm delivers maximum pull-out resistance, while the black zinc plated finish blends seamlessly with dark hardware and interior fittings. This pack contains 200 pieces.

Product description

  • Multifunctional application indoors
  • Fast and reliable processing with low effort (more screws on one battery charge)
  • Application in decorative furniture construction when using dark/antique woods or dark furniture/metal fittings

  • Visually attractive appearance with black fittings and dark wood types
  • Without pre-drilling (depending on the type of wood)

The universal screw is the absolute all-rounder in the SPAX 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 practically completely prevented.

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