This set of sockets is designed to remove exhaust temperature sensors.

Due to heat cycles and the corrosive environment in the modern diesel exhaust system the EGT sensors become very difficult to remove without damaging them.

This set of sockets is designed to drive all 6 sides of the hex equally to reduce the chance of damage.

The 3 different sizes and two different styles will remove most if not all EGT sensors used on cars, light, medium, and heavy-duty trucks on the road today.
