Some versions of the Polydrive systems have more lobes in the fastener heads, although this isn’t common. Torx vs. Polydrive (RIBE) Screws A key advantage of the Torx system is that is allows higher torque transmission than other drive systems enabling fastenings to be tighter and therefore more secure.

could happen on cheap fasteners. Motorcyclists have been using them for years, as the exterior of many bike have Phillip head fasteners, and one likes to keep them looking good. As both a motorcyclist and an avid classic car collector, these or the only tools I use on my machines for Phillip head fasteners. This snug fit allows for greater torque transfer. The Torx Plus screws can be tightened more securely than their Torx counterparts. More secure installation means the workpiece is held together more securely, leading to greater durability. Torx bits are a specialized type of screwdriver bit designed to prevent slips. They’re a standard 1” length and have a flattened, six-pointed head. For this last reason, they’re generally known as star bits. BenefitsMany star bits have little improvements, such as knurled ends or ball dents to improve handle grip. While essentially the same as official Torx, these little additions tend to make third party star bits a more popular choice. Internal vs External Torx External Torx While it’s common to use the terms Torx and star interchangeably, there’s actually a bit of a difference between the two. Much like the Allen wrench, Torx is a trademarked name and refers to a specific brand, whereas star is the generic name (much like hex keys). However, there is a difference beyond just licensing. The standard Torx driver bit or the key will work on the Torx Plus, but it’s not a perfect fit and can lead to wear or damage. Torx and Torx Plus are similar fasteners, but Torx Plus optimizes the design of the original Torx. While both have a six-point connection with the drive head, the Torx fastener allows for a 15° drive angle, while the Torx Plus has a 0° drive angle. This increases the available torque and minimizes wear on the fastener and drive head. The Polydrive, or RIBE, is a fastener similar to the Torx. To the untrained eye, they may even look interchangeable. These fasteners also have a spline-shaped geometry with rounded ends, cut as a recess into the fastener head, that allows secure fastening, increases torque transfer, and minimizes cam-out.

Here’s a summary of just some of the issues associated with various typical, commonly used drive systems. Hex Drive The Torx Plus screw is ideal for high torque transfer and low head height applications. In short, applications where the screws must be tightly fastened but also fit in a small space.The modified geometry improves durability and maximizes the torque available to the fastener. This increased torque allows the fastener to be fastened more securely without stripping the screw head. Sidewall Difference
