SPAX 4CUT cutter
The SPAX 4CUT cutter (or simply SPAX 4CUT) is the square shape of a SPAX at the transition from the thread to shaft. This has the advantage of reducing the driving torque by up to 60%. As a result, the SPAX can be screwed in smoothly and with little effort – and helps battery-powered drills hold their charge for longer. The SPAX 4CUT cutter is generally reserved for screws 160 mm long and longer.
