EXPEDIUM VERSE Screws have a fully threaded, tapered tip
minimizing the need to tap. However, taps are provided for
surgeon preference.
Clear surrounding soft tissue and bony anatomy to allow
for full screw angulation.
Choose appropriate tap size per table.
Start with a smaller tap diameter and complete sequential
tapping steps, increasing tap diameter until the desired
diameter is reached. It is recommended to limit the change
in hole diameter by one size and to tap to the full length of
the screw intended to be placed.

NOTE:
In order to decrease the amount of torque
required for large diameter screws, the degree of
undertapping has been reduced for the 8mm tap.
