With a tamper-resistant Torx or Torx Plus drive (also known as a pin-in Torx or Torx Plus drive), these screws are difficult to remove without special tools. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Install Torx screws using tamper-resistant Torx drivers and bits.
Torx Plus screws have more points of contact than hex drive screws, so you can tighten them with less slippage and damage to their recess. These tamper-resistant Torx Plus screws have five lobes. Install them with tamper-resistant Torx Plus or tamper-resistant pentalobe drivers and bits.
