Pull out strength is not affected provided theself tapping flutes lie outside of the cortex. Add an extra1mm when assessing screw length.IMPROVEDDESIGNIMPROVEDDESIGNSelf Tapping Screws are less effective in dense cortical bone.e.g. calcaneus. It is advised that an appropriate tap be available shouldthe need arise.

Self tappingflutes at the tip obviate the need for pre-tapping whichsaves time and reduces time related complications. Pull out strength is notaffected provided the self-tapping flutes lie outside the bone cortex. Allowan extra 1mm when assessing screw length.
