Pozidriv Screws – Buy a Pozidriv Screwdriver Online

Pozidriv screws, often incorrectly named Pozidrive screws, are a derivative of the Phillips screw, designed to negate many of the disadvantages associated with that screw type. Superficially, the Pozidriv screw resembles the cruciform Phillips screw, but closer inspection shows that the Pozidriv screw incorporates four extra tick marks at 45-degree angles to the main recess, and Pozidriv screws do not have the rounded corners common to Phillips screws.

Unlike Phillips screws, Pozidriv screws do not cam out under conditions of high torque, a trait that was advantageous in the early days of mass production, because it prevented over-tightening of the screws and reduced the resulting risk of stripping the screw or damaging the product.

With the advent of power tools that automatically disengage if torque exceeds desired levels, this is now seen as a disadvantage, and the Pozidriv seeks to negate this. Despite this, the Pozidriv screw never became popular in North America, although they are very common in Europe.

The Advantages of Pozidriv Screws

• Pozidriv screws do not cam out under high torque, making it easier to drive self-tapping screws into hardwood or prevent machine bolts from loosening under conditions of high vibration
• Unlike star drive and hex heads, you can use a slightly larger or slightly smaller Pozidriv screwdriver, ensuring that you need fewer drivers in your set
• The screw can be engaged in four positions, making them a better option than slotted screws in restricted spaces

The Disadvantages of Slotted Head Screws

• Pozidriv heads are very hard to find outside Europe, and they are not available in a wide range of styles or types
• It is very easy to mistake Phillips heads for Pozidriv heads, and vice versa. To a certain extent, Pozidriv and Phillips head screwdrivers are interchangeable, but using the wrong type can damage screw or driver
• If the user overtightens the screw, this can damage the screw recess, strip the thread, or damage the driver
