TORK CRAFT SCREWDRIVER POZI No.3 x 150mm

Pozidrive:

The drive is an improved version of the Phillips drive. Greater torque can be applied on a Pozidrive screw. The Pozidrive screws and the screwdriver can be distinguished by a second set of radial indentations set at a 45° from the cross recess. The design is intended to decrease the likelihood that the Pozidrive screwdriver will slip out. The disadvantage of the Pozidrive is that is visually similar to Phillips and that many people are unaware of the difference or do not own the correct screwdrivers.

Phillips:

The drive was invented by Henry F. Phillips. The Phillips screws have cross-slots that look like an X stamped into the head. The drive was patented in the 1930’s. This drive was invented to become a vast improvement from the antique slotted screw, which tended to cam-out easily. Nowadays, the Phillips screw is easily mistaken for a Pozidrive screw.

IMPORTANT:
The screws having a pozidrive head can be unscrewed by a Phillips screwdriver, but a Phillips screw cannot be unscrewed by a Pozidrive –  It will severely damage the screw and the tip of the screwdriver.
