Strong wood joints with Spax screws
- Optimal drive power transfer: The T-STAR plus T20 recess provides a secure bit fit and prevents cam-out during fast driving.
- Clean flush surface finish: The countersunk multi head with ribs sinks neatly into the timber without tearing the wood fibres.
- Superior corrosion resistance protection: With the exclusive WIROX surface coating, you achieve significantly higher protection against corrosion than conventional zinc plating.
With the Spax wood screw 3,5 x 20 mm, you achieve strong and neat timber joints with total confidence. The t-star plus T20 recess provides a secure bit fit and optimal torque transfer, preventing cam-out and bit slippage while driving. Its multi head with ribs sinks cleanly flush into wood and stops safely against metal fittings without damaging them. Thanks to the full thread, you get maximum pull-out resistance, making it an ideal choice for cabinet making, interior fittings, and fixing thin board materials. Furthermore, the specialized wirox coating delivers significantly higher corrosion protection than standard zinc plating, ensuring durable and reliable fastening.
