What is a Pozi Head?
The Pozi ScrewDriver was invented to further improve on the torque of the Phillips head screwdriver. To do this there was a second cross added to the first cross. This not only helped when distinguishing between the two head types, it also further improved the contact of the driver to the screw.
We have a wide variety of pozi head screws. For more information please call us on 01243 551484 or email [email protected]
