Spax wood screws with hexalobular socket Ø 4 x 30 mm

These 30 mm long countersunk head wood screws from Spax are made of rustproof, non-ferromagnetic stainless steel and fit most of the screw-on magnets and pot magnets with countersunk holes in our assortment. Thanks to the countersunk head, the Spax wood screws can be fastened flush in the hole of the magnet. In addition, these wood screws have a special 4CUT point to reduce the fastening torque and displace excess wood when tightening, making it less likely that the wood will split.

Since the Spax wood screws are made of stainless steel, they are suitable for indoor and outdoor applications. The non-magnetic material of the screw makes it much easier to attach the magnet because no adhesive forces are acting on it. Of course, you can also use these countersunk screws for projects without magnets, for example, to attach wooden strips or wood panels.

The hexalobular wood screws from Spax are compatible with the following screw-on magnets and pot magnets with countersunk holes:
