With the Spax Spax-M mdf screw, you assemble panels and furniture securely, quickly, and without splitting. Thanks to the cut point, you drive directly into mdf and thin wood-fiber boards without pre-drilling, keeping edges and board ends neat and intact. The partial thread pulls board materials tightly together without gaps, while the countersunk head sinks flush into the surface. The t-star plus T15 drive recess delivers dependable stability and torque transfer without bit slip. In addition, the wirox coating protects the steel against abrasion and corrosion. This pack includes 200 screws measuring 3.5 x 45 mm for all your interior joinery projects.
