Cutter screws have a tropicalized coating which provides superior corrosion resistance compared to the standard BZP coating, along with a deep countersunk head recess which ensures a snug fit with the driver bit preventing "cam out".
As a result of the lubrication, sharpness, width, and depth of the thread, it reduces driving resistance by 40%, which means less torque is required.
THe R2 thread pattern along with the 25° needle point gives the abilty to penetrate almost all timbers without a pilot hole.
