With the Spax-M mdf screw, you join mdf and fiberboard securely without splitting the material, even when fastening close to the edge. Thanks to the specialized cut point, you drive directly into panels without pre-drilling, saving valuable time during furniture making and interior joinery. The milling ribs beneath the small countersunk head cut cleanly into the wood fibres, delivering a smooth, flush finish without bulging. The partial thread draws the top board tightly against the supporting structure for a gap-free joint. With the t-star plus T20 drive, you maintain stable bit engagement without slipping, while the Wirox coating provides dependable corrosion resistance.
