Build strong and tight wood joints with the Spax s chipboard screw 0291010450505. The partial thread with a thread length of 32 mm draws wooden boards firmly together without gaps, making it ideal for furniture making, framing, and fastening sheet materials. Thanks to the countersunk head, the 4.5 x 50 mm screw sinks cleanly and flushes neatly with the timber surface without splitting the wood. The PZ2 drive delivers solid bit engagement during fastening, while the chromium-free wirox coating provides superior corrosion protection for indoor and covered outdoor projects. This pack of 500 pieces gives you plenty of screws for your carpentry and interior fitting work.
