Strong wood fastenings with Spax chipboard screws
- Enhanced Wirox corrosion protection: The specialized Wirox coating shields the zinc-plated steel significantly better against corrosion than standard zinc coatings.
- Clean countersunk finish: The countersunk head with brake ribs sinks cleanly into the wood surface without tearing the fibers.
- Maximum grip through full thread: Featuring a full thread design and a PZ1 drive, you achieve dependable holding power across timber connections.
With Spax s chipboard screws 3 x 40 mm, you achieve strong and clean timber fastenings with ease. The countersunk head with brake ribs sinks smoothly into the surface, delivering a neat and flush finish without damaging the wood fibers. Thanks to the full thread design featuring a 36 mm thread length on a 40 mm screw, you obtain maximum pull-out resistance and reliable holding power in chipboard, MDF, and solid wood. The specialized Wirox coating provides enhanced corrosion protection compared to standard zinc plating. Paired with a precise PZ1 drive, these screws give you full control during furniture assembly and indoor carpentry projects.
