With the Spax wood screw 6 x 140 mm, you achieve strong and seamless timber joints with ease. The partial thread pulls thick wooden beams and battens tightly against the substrate without leaving gaps. Thanks to the t-star plus T30 drive, you benefit from a secure bit fit that prevents cam-out and ensures optimal torque transfer. The countersunk multi head sinks neatly and flush into the timber surface without damaging the surrounding fibres. In addition, the Wirox coating provides reliable corrosion protection for your interior and sheltered outdoor construction projects.
