Spax Self-tapping screws M SK T20 4.0x45 mm

The most popular wood-based panels in furniture construction are the so-called MDF boards. MDF stands for medium-density fibers, meaning these are very fine-pored and homogeneous furniture panels, whose edges, unlike particle boards or coarse particle boards, can be screwed and nailed. However, MDF boards tend to warp or split at the edges when screws are driven into non-pre-drilled edges. To prevent this, we developed SPAX-M: the combination of a CUT tip that essentially drills its own screw hole, a razor-sharp wave profile, and a small 75° milling head for flush sinking of the screw ensures that you can easily screw your MDF components together. However, we recommend maintaining a minimum edge distance of 25 mm from the panel edge even when using SPAX-M. This means for you: secure edge screwing, no splitting of the panel edges.
