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. Can You Remove a Torx Screw Without a Torx Bit?.
