EJOFAST® wood screw JF3-6,8
self-drilling screw JF3-6.8 is particularly suitable for the fastening of sandwich panels and trapezoidal profiles to timber substructures without any swarfs. The self-tapping wood screw drills through the sandwich panel or the trapezoidal profile virtually without any swarfs - thanks to its innovative combination thread which combines the positive characteristics of two different thread geometries.
The point has the renowned EJOFAST®
thread geometry. This geometry grinds the wood fiber and replaces the pre-drilling. The thread merges into a wood screw thread with a diameter of 6.8 mm. Its high pitch diameter offers excellent pull-out values in wood.
