💡 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
