💡 What's the difference between Torx and E-Torx sockets?
Torx bits fit into a star-shaped recess, while E-Torx sockets fit over a star-shaped bolt head.

  • Torx bits are for internal star screws on brakes, trim, and electronics
  • E-Torx sockets grip external star bolts common on European cars
  • Plenty of shops keep both since many vehicles use each type
