What Are Pozidriv Screws

Posted on 29/08/22


In the case of Pozidriv screws, these screw fasteners have external threads and torquing heads with radial indentions that are set at 45 degrees to the main cross, utilizing a cruciform socket with radial indentations.
  
One of the most common screw drives used worldwide is the pozidriv, which is a type of screw drive that is used on sockets and drivers. The Pozidriv trademark, also known as PZ or PSD (or mistakenly spelt, "Pozidrive"), is owned by Phillips Screw Company and is often abbreviated by PZ or PSD. GKN Screws and Fasteners, however, patented the drive in 1962 as an improvement on Phillips screw drives as an improvement over the Phillips screws.  

In order for Phillips screwdrivers to work correctly, they are designed with cruciform sockets that have rounded corners and an angle on the flanks, which is designed to "cam-out," which means that when the correct torque is reached, the driver will throw out the screwdriver. This means that when the screwdriver is turned, it will slip out of the head of the screw and can cause the screw to fall out.  

The Phillips screw drive is precisely aligned with the surrounding material, reducing the possibility of slippage and the associated damage to the surrounding material. Compared to slotted drives, a cammed drive ensures the screw will not be marred or broken as it automatically “cams out” when it is being used.  

The cam-out feature of Phillips screws was preferred by aircraft and automotive manufacturers for this reason, but in the end, the cam-out feature did not prove to be used by everyone. Pozidriv screws were developed for this purpose, and that is the reason why they were invented.  

There are parallel flanks on the Pozidriv, as well as two additional ribs on the main cross, which work together to create a highly efficient driver, reducing cam-out, and enhancing heat transfer. In addition to allowing for greater torque and reducing worker fatigue, this allows for reduced screw damage, driver wear, and screw damage. The installation speed is also increased as a result of it.  

There are two categories of Pozidriv screw drives: the smallest and the largest. Typically, their abbreviated form is accompanied by a number 0 through 5. A generic fastener known as a PZ-1, a PZ-2, or a PZ-3 is a fastener that is used in a variety of applications, especially in the construction, manufacturing, and engineering fields.  

In the UK, they are the de facto standard for construction screws throughout the country, and they are among the most commonly used screwdriver types globally. The PZ-1, PZ-2, and PZ-3 machine screws are available with a variety of head styles. Among the head style options are countersunk, non-countersunk, self-tapping, and self-drilling heads.  

In the material world, the smallest Pozidriv socket is the PZ-0, which is frequently used to attach small components to masonry, such as computers and electronics. In the material world, the largest Pozidriv socket is the PZ-4, which is used to attach frames to structures, for example, when mounting windows and doors.  

These fasteners have some disadvantages, one of which is that they look very similar to Phillips screws, making it often difficult to choose the proper driver for them. It is true that Pozidriv drivers are not compatible with Phillips screw sockets, but Phillips drivers are compatible with Pozidriv screw sockets. There are some screws that can turn, but they will typically ride out of the socket when you are turning them, causing the fastener and the driver to round off at relatively low torques, which is not a good thing.  

As a direct successor to the Pozidriv, the Supadriv has been designed by GKN Fasteners as a stand-alone product. It is suitable to drive Supadriv screws with Supadriv drivers, which are interchangeable with Pozidriv drivers and are similar in appearance and function to these devices. By doing so, a superior bite can be obtained, allowing a slight angular offset, reducing cam-out, and improving efficiency when driving Supadriv screws.  

There are two radial indents on the surface of Supadriv screws, which makes them more difficult to distinguish from Pozidriv fasteners. There are four parts to a Pozidriv head.
