With the Spax universal screw 4.5 x 50 mm, you achieve robust and reliable joints in timber construction and interior finishing. Thanks to the full thread design, you benefit from high pull-out resistance and solid fastening strength when working with chipboard, MDF, and solid wood. The PZ2 Pozidriv recess provides dependable bit grip to prevent slipping, keeping you in complete control while driving each screw. The countersunk multi-head cleanly cuts into the material without pre-drilling in softwoods, delivering a smooth, flush finish. Furthermore, the Wirox coating shields the steel against corrosion in all indoor and sheltered outdoor applications.
