By design, TORX® compatible head screws resist cam-out much better than Phillips or Slotted screws. Where Philips heads were designed to cause the driver to cam out, to prevent over-tightening, TORX® compatible heads were designed to prevent it and to achieve a desired torque consistently. TORX® compatible head sizes are described using the capital letter 'T', followed by a number. A smaller number corresponds to a smaller point-to-point dimension of the screw head. Only the proper driver can drive a specific head size without risk of ruining the driver or screw.
High-Low Thread screws have excellent holding power in wood due to their alternating high and low thread heights.
