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.
