While essentially the same as official Torx, these little additions tend to make third party star bits a more popular choice. Many star bits have little improvements, such as knurled ends or ball dents to improve handle grip. Yet star bits are so closely matched to the shape of Torx that they can easily be used as a substitute. Many consumers feel that star bits are better than Torx because the latter uses a restricted manufacturing license to use the patterns. However, there is a difference beyond just licensing. 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). While it’s common to use the terms Torx and star interchangeably, there’s actually a bit of a difference between the two. But you may also find them used in home appliances. For this reason, it’s a popular fitting for prisons and other high security or high risk areas. Without the proper bit, you won’t be able to manipulate the security Torx screw. The pin serves to block access to the screw with regular Torx bits, as well as other driver types. The big difference is the addition of a central pin. Much like the regular star heads, these tamper proof Torx heads have a six-pointed recess. To combat this, a special variant called the Torx security fastener was created. Torx vs Security TorxĪs Torx became more common, it also became less secure. There’s even a Torx security variant that provides maximum tamper resistance. You can apply a large amount of torque without camming out.įinally, Torx bits are less common, making it more difficult for theft, vandalism, and other forms of unauthorized access. As a result, it can be very difficult to slip when applying torque to a Torx bit.Īnother advantage over other types is that star bits are much more efficient when hand-tightening. The star shape provides six points of contact, and the tip is flat, allowing for maximum contact. Star bits take the strengths of each and improves upon them. Phillips bits have four connection points but usually also has a tapered tip that contributes to slippage. However, they also have a flat edge which increases overall surface contact. Straight bits have only two points where they grip the screw, making it easy for them to strip the head. BenefitsĪs mentioned, one of the reasons the Torx driver was invented was to reduce the risk of slippage when applying torque. For this last reason, they’re generally known as star bits. They’re a standard 1” length and have a flattened, six-pointed head. Torx bits are a specialized type of screwdriver bit designed to prevent slips.
