Product description
The cross recess Z is a further development of the cross drive by the Phillips Screw Company. The difference is that the four flanks of the screwdriver blade do not taper towards the tip. This increases the lateral hold for the screwdriver bit and reduces the cam-out effect. Typical tapering on conventional cross recess drives causes this to happen, since the cordless screwdriver torque pushes the screwdriver bit upwards.
The countersunk head (also known as the flat countersunk head) has a polygonal underside (“pockets”) that mills its way into the wood and can therefore be countersunk without having to pre-drill the screw hole. The flat countersunk head sits flush with the surface.
The screws with partial thread are ideal for fastening thin components like engineered wood boards, panels and floorboards to thicker components like squared timbers or beams. The short thread penetrates the thick component, whilst the thread-free shank remains in the attachment. This creates maximum contact pressure between the two. The thread-free part should be at least the same thickness as the attachment.
