KTX is a specially developed and patented head recess that offers significant advantages to other screw recesses. The head will take KTX, Pozi, Square and Philips screw bits and it has a deep recessed head for good engagement with the screw bit. All the screws are precision manufactured using hardened steel and each box is accompanied with a 50mm KTX screw bit free, as the screw bits and screws come from the same manufacturer they offer perfect fit.
It’s the case with other head recesses such as Pozi and Torx the heads vary slightly and its also true that the screw bits vary too which means that there are fractions of differences in the heads which allow for movement, wobbling and slippage and ultimately means that something is lost between the power tool / screwdriver and the screws. The KTX head is a stick fit which allows the torque and rpm of the power tool to work through the screw and when working in hard materials like MDF, Chipboard or Hardwood the screw has fast penetration and so saves time and effort.
