With Spax s chipboard screws 4 x 40 mm, you can easily create strong and neat wood joints in furniture making and interior finishing. The 4CUT screw point allows fast driving without pre-drilling while effectively preventing wood splitting. The countersunk multi head mills smoothly and flush into the surface, delivering an even finish without protruding screw heads. Thanks to the full thread design, you achieve maximum grip and high pull-out resistance across the entire length in materials like chipboard and MDF. The Pozidriv PZ2 drive prevents cam-out and stripping, while the Wirox coating provides high corrosion protection in dry indoor areas.
