With Spax s chipboard screws, you assemble timber structures, chipboard or mdf furniture, and skirting boards quickly and reliably. The special screw point and thread prevent wood splitting, making pre-drilling unnecessary in softwoods. The countersunk multi-head countersinks flush and cleanly into the wood surface without damaging the material, while braking against metal to prevent over-tightening during hardware installation. The Pozidriv PZ2 cross recess minimizes bit cam-out for steady torque transfer. Additionally, the full thread delivers maximum tensile and compressive holding power along the entire length, while the Wirox coating ensures reliable corrosion protection for indoor applications.
