As seen, the Pozidrive head incorporates a blunt nose, with an additional blade in between four intersecting driver blades. Pozidrive was originally developed to be the new and improved Phillips. As Phillips was developed to have more purchase on the drive than a slotted head, Pozidrive was yet another enhancement. They do the same thing, the do that thing well, but the one is designed for much more grip and purpose under lots of torque. Phillips vs PozidriveĪnalysis: Comparing Phillips and Pozidrive (PZ) is like comparing an off-road tire to an all-weather tire. This is precisely why fastener companies have developed heads for various applications.
Fasteners are simply not tough enough to handle excess torque in the neck of the fastener, but usually, cam out happens far before over-torquing can cause the fastener to snap. So basically, when you use your impact on setting 3 and continue to drive when the material will not let the fastener travel any further, you’re going to have cam out. “The overexertion of torque on a given fastener head, resulting in the distortion of the driver purchase area, ultimately leading to the failure of the fastener head.” As defined by me, a self-proclaimed garage engineer, “Cam Out” is… Most importantly, before we can get into driver head types, we’ll have to address the why. Like Wera, a lot of German tools tend to last very long in the field and always do the job without a hitch. KC Tool sells some of the best quality tools on the market, specifically ones made in Germany.

Thankfully, our awesome friends at KC Tool were able to hook us up with Wera drivers for this informational article. While it would be a crazy challenge to look into all driver head types, this article will explore some of the more uncommon, yet popular driver heads that you may run into. In some cases, specific industries were targeted during development.
But what’s important to remember is that all of these heads were developed for a specific purpose. It’s easy to forget just how many driver head types there are, especially if you’re used to only a few. Everything else might look a little foreign! So let’s dive in and take a look at Driver Bit Types explained. For most DIY’ers, and homeowners, the standard Phillips, and slotted (AKA flathead) are pretty much standard around the house. You go to the hardware store and grab the right length fastener for the job, then get home and darn it – it’s got a different head than what you wanted! Either this or you send someone else to the hardware store and they do the same thing! Though depending on what trade you’re in (if you’re in one) driver heads might be the same in your day-to-day.
