With the Spax s chipboard screw in 4 x 30 mm, you can easily create strong and seamless wood joints. Thanks to the 18 mm partial thread, you can draw wooden components and sheet materials tightly together without gaps. The countersunk multi-head mills smoothly into the timber to deliver a clean, flush finish without splitting the surface. The PZ2 drive provides a secure, non-slip fit during driving, while the Wirox coating ensures reliable corrosion protection for all your interior furniture assembly and woodworking projects.
